The supercontinuum optical pulse source further comprises a first microstructured light-guiding member (9) arranged along the first optical path and configured to generate supercontinuum light responsive to an optical signal propagating along said first optical path, and a second microstructured light-guiding member (9) arranged along the second optical path and configured to generate supercontinuum light responsive to an optical signal propagating along said second optical path. The supercontinuum optical pulse source further comprises a supercontinuum-combining member (5) to combine supercontinuum generated in at least the first and second microstructured light-guiding members to form a combined supercontinuum.

    Abstract: A wavelength converter which employs an optical fiber and has high converter efficiency. The polarization planes of a signal light and an exciting light outputted from a laser diode (LD) (103) are respectively controlled by polarization controllers (PC's) (101 and 104) and the phases of the lights are respectively modulated by phase modulators (PM's) (102 and 105) in accordance with modulation signals outputted from an oscillator (110). Then, the output lights from the PM's (102 and 105) are multiplexed by a coupler (106). After the multiplexed signal light and exciting light are amplified by an optical amplifier (EDFA) (107), they are inputted to a dispersion shift fiber (DSP) (108). After wavelength transformation (four light waves mixing (FWM)) is practiced in the DSP, an FWM light is outputted through a band-pass filter (BPF) (109).

    Abstract: A wavelength conversion module comprises an external resonator, a semiconductor laser module, and a wavelength conversion device for converting the wavelength of the light emitted from the semiconductor laser module into a wavelength shorter than the former wavelength. This wavelength conversion device can be at least either a nonlinear crystal for generating a sum frequency (SFG) or a nonlinear crystal for generating a second harmonic (SHG). In the sum frequency (SFG) generating element and second harmonic (SHG) generating element of the wavelength conversion device, the periodical polarization may be inverted by a ridge optical waveguide structure or by a proton-exchange optical waveguide structure.

    Abstract: A wavelength tunable light source includes an optical pulse generating section (101) for generating an optical pulse; an amplitude control section (102) for controlling the amplitude of the optical pulse generated by the optical pulse generating section by superimposing control light on the optical pulse to output a short optical pulse; and an optical frequency converting section (103) for converting the frequency of the short optical pulse by launching the short optical pulse output from the amplitude control section into an optical nonlinear medium whose refractive index varies in response to the electric-field intensity of the incident light. The amplitude control section can be configured such that it carries out the time division multiplexing and outputs the short optical pulse, thereby constituting an optical pulse light source.
