Abstract: A blazed grating, in particular of the microfabricated type, is disclosed as well as mode hop-free tunable lasers in which this grating is employed, and a process for fabricating gratings of this type. The grating lies in a general plane and comprises a plurality of elongate beams carrying mutually parallel respective reflection surfaces spaced apart from one another with a predefined pitch, each of these reflection surfaces having a normal direction inclined at a grating angle a to the normal direction of the general plane. Furthermore, the grating comprises a plurality of resilient suspension arms connected to the beams and intended to be fastened to a grating support. The suspension arms, the beams and their respective reflection surfaces define an assembly formed from a single part. A first pair of comb electrodes is provided for applying a mechanical force to this assembly, these being placed on a first side of the grating, along an axis transverse to the beams, and designed so as to allow the pitch of the grating to be modified in response to the application of the mechanical force. A second pair of electrodes placed on the opposite side from the first allows, in combination with the first pair, application of a displacement of the assembly, possibly without deforming it. It is thus possible to modulate the wavelength and/or the phase of a light beam with a device that is simple and inexpensive to fabricate and has a small footprint.

Abstract: A monochromator for use in a spectrograph admits light from an aperture to a primary reflector (preferably an off-axis parabolic mirror) which collimates the input light with low aberration and directs it to a diffraction grating. The component wavelengths of the input light are then directed to first and second secondary reflectors (preferably spherical or toroidal mirrors), which are chosen to cooperatively focus the component wavelengths in ordered bands across an array detector while each at least substantially cancels the effects of any aberrations introduced by the other. By choosing optical elements which supply the grating with input light with low aberration, and then choosing optical elements which receive the component wavelengths from the grating and which offset any aberrations introduced by the other receiving optical elements, wavelength resolution at the detector can be enhanced.

Abstract: [Purpose] The object of the present invention is to provide a spectroscope having both a wavelength resolving power and a spatial resolving power.
[Solving Means] A spectroscope comprises an incident slit 12, a collimator lens type optical system 14 that makes the light rays having passed through the incident slit 12 parallel light rays, a reflection type diffraction grating 16 that receives the parallel light rays and, according to the wavelength, outputs these light rays at different angles, a condenser lens type optical system 14 that condenses the output light from the diffraction grating 16, and two-dimensional light-receiving means 16 having a two-dimensional light-receiving surface that detects the light rays that have been condensed by the condenser lens type optical system. The collimator lens type optical system and the condenser lens type optical system are disposed so that the angle 2γ defined between the optical axis of the collimator lens type optical system and the optical axis of the condenser lens type optical system may be acute; the condenser lens type optical system is disposed so that the distance between itself and the diffraction grating may be shorter than the distance between the collimator lens type optical system and the diffraction grating; and a setting is made so that a normal line vector at the central portion of the reflection surface of the diffraction grating may be directed, from a bisector of the angle defined between the optical axis of the collimator lens type optical system and the optical axis of the condenser lens type optical system, toward a side where the collimator lens type optical system is disposed.

Abstract: A small-sized and low-cost wavelength division multiplexer having little insertion loss, little polarization dependence and a broad wavelength bandwidth,    the wavelength division multiplexer adopting a grating configuration in which an incident light is retroreflected, exit lights from respective grooves are enhanced by interference effect in the incident direction of the light, wave surfaces of evanescent waves in the grooves are parallel to the normal direction of the grating and phases of the evanescent waves in the respective grooves agree with each other. The wavelength division multiplexer has high diffraction efficiency in each of TM and TE polarized lights at a several-order diffraction order and accordingly has a broad wavelength bandwidth and remarkably low polarization dependence.

Abstract: An optical system having a first order spectral range that is usable in an optical spectrum analyzer receives an broadband optical test signal and a optical calibration signal and couples the optical signals via two optically isolated paths to separate optical detectors. First and second pairs of optical fibers, with each pair having an input fiber and an output fiber, are positioned in a focal plane of a collimating optic that has an optical axis. The fiber pairs are symmetrically positioned on either side of the optical axis with the input fibers positioned on one side of the optical axis and the output fibers positioned on the opposite side of the optical axis. The input fibers receive the optical test signal and the optical calibration signal. The output optical fibers are coupled to first and second optical detectors. An optical calibration source generates second order or greater spectral lines that fall within the first order spectral range of the optical system. A diffraction grating receives the optical test signal and the optical calibration signal from the collimating optic and separates the first order spectral components of the broadband optical test signal and passes the second order or greater spectral lines of the optical calibration signal. The first optical detector that is responsive to the first order spectral components of the optical test signal receives the optical test signal from the collimating optic and converts the optical test signal to an electrical signal. A second optical detector that is responsive to the second order or greater spectral lines of the optical calibration signal concurrently receives the optical calibration signal from the collimating optic and converts the calibrations signal to an electrical signal.

Abstract: A spectrum analyzer providing an integrated calibration function and for providing that calibration function automatically. The injection of light to be analyzed through a central aperture (14) of a scanning grating (12) onto a focusing reflector (16) provides in combination four traversals of the space therebetween. The spectrometer thus is used to separate wavelength information spacially and receive it back at the same or adjacent aperture(s) (14) to be analyzed by a processing system (50) to establish the spectra for the incident light. The light is typically injected from and received back into optical fibers (42, 46) or other light carrying elements. Calibration light is also applied through the same or adjacent apertures (14) in the grating (12) from a known source and spectra such as Argon to use as a calibration reference by detecting the known spectra peaks and correlating it to grating scan angle. The same structure is also used as a telecommunications channel router.
