    Abstract: A method of fabricating microelectromechanically tunable vertical-cavity surface-emitting laser (4) and microelectromechanically tunable Fabry-Perot filter (2) with precise lateral and vertical dimensional control is disclosed. Strained reflective dielectric film stack (6) are applied to multiple quantum-well structure to electronically band-gap-engineer the quantum wells. Strain in the reflective dielectric layers is used to create a curvature in one of the reflective dielectric film stacks to form a confocal-cavity (8) between a planar reflective dielectric film stack (10) and a curved reflective film stack (12) in the laser or filter, which are also provided with suspended membrane structure (37) that supports a cavity-tuning dielectric film stack, while being anchored at the perimeter by a meatal support posts (38). Precise air-cavity length and lateral dimensions are achieved by micro-die-casting using a sacrificial material of polyamide or aluminum.

    Abstract: An optical fiber wavelength reference device (110) for tuning a tunable Fabry-Perot filter (105) and/or a tunable VCSEL (105) to a desired frequency, where the device uses a fiber etalon (120) to generate a pattern of reference frequencies against which the device is tuned. In addition, the device uses a detector (125) to monitor the output of the Fiber Etalon (120). The ouput of the detector (125) is inputed to a controller (115) used to control the VCSEL (105) or tunable Fabrey-Perot filter (105).

    Abstract: A compact wavelength monitoring and control assembly (110) for a narrow band (i.e., laser) source is provided, comprising two narrow bandpass, wavelength selective transmission filter elements (130, 160) of Fabry-Perot structure through which two separate collimated beams from a laser source are directed onto two photodetectors (145, 175). A control circuit processes the simultaneously acquired signals from the two detectors (145, 175) as the laser wavelength is varied. The device functions as an optical wavelength discriminator in which the detectors (145, 175) convert optical energy to current (or voltage) for a feedback loop for controlling the laser source. Any one of a large number of discrete, predetermined wavelengths may be chosen for locking using the same device.

    Abstract: A fiber connector that facilitates alignment of and electrical communication with electrooptical devices on an optical fiber or interposed between optical fibers. An embodiment of in-line optoelectronic device packaging (10) constructed according to principles of the invention includes a ferrule (20) configured to receive an optical fiber with an optoelectronic device (D) mounted on one end of the ferrule, for alignment with the fiber. Electrically-conductive deposits (30) along the side of the ferrule supply electical energy to or conduct electrical signals from the optoelectronic device (D). The optoelectronic device-carrying ferrule is inserted in a ceramic sleeve (40). Another ferrule (120), maintaining another optical fiber (115), also is inserted in the ceramic sleeve (40). Another embodiment constructed according to principles of the invention includes a second optoelectronic device mounted on the second ferrule (120). The electrically-conductive deposits permit ready serial deployment of optoelectronic devices, such as a variable attenuator or VCSEL laser emitter, between the optical fibers maintained by the ferrules in the sleeve.
