摘要： A wavelength monitor is provided based on the transmission response of an optical filter. The monitor provides feedback to the laser enabling it to lock to any given wavelength within its tuning range. The invention is also a process for integrating the wavelength monitor directly on chip with a variety of tunable semiconductor lasers. The invention also comprises a method for controlling the wavelength of a tunable laser by using a wavelength monitor to measure the output light and provide feedback to a control system. The laser and wavelength monitor are integrated together on a single indium phosphide chip. The wavelength monitor comprises a filter with a wavelength dependent transmission function and a pair of detectors. One detector is illuminated with light that has passed through the filter and the other provides a reference to measure the input intensity. Taking the ratio of the filtered light level to the unfiltered light provides a wavelength dependent wavelength. The filter is designed such that the transmission function is monotonic and varies from a minimum at one extent of the laser's tuning range to a maximum at the other extent.

The device comprises a layer of semiconductor material, a first layer, and a second layer. The first layer is indium arsenide and is coupled to the layer of semiconductor material, wherein the first layer of indium arsenide is under a compressive strain by a lattice mismatch between the layer of semiconductor material and the first layer of indium arsenide. The second layer is aluminum arsenide and is coupled to the layer of indium arsenide, wherein the second layer of aluminum arsenide is under a tensile strain by a lattice mismatch between the second layer and the first layer. The first layer and the second layer comprise a digital alloy of aluminum indium arsenide, and create a quasi-strain-compensated substantially defect-free alloy on the layer of semiconductor material therein. A superlattice period of the first layer of indium arsenide and a second layer of aluminum arsenide is selected to allow an oxide of desired depth to be produced from the digital alloy.

摘要： A low cost, high speed WDM optical link which employs a circular array of VCSEL emitters directly coupled to a multi-mode fiber through which multiple simultaneously optical transmissions are sent to an optical detector comprising a circular array of RCPD detectors receiving the multiple simultaneous transmissions. The emitters and detectors within each array are fabricated with a double-absorber design which avoids position sensitivity related to the cavity standing wave and eliminates the need for in-situ cavity-mode adjustment. In addition, a coupled-cavity structure is presented to achieve passbands with flat tops and steep sides to approach the ideal square-shape photoresponse and to ensure proper channel alignment.

摘要： An improvement for allowing selective tuning of the emitted beam over a broad bandwidth to a diode laser having an active section for creating a light beam by spontaneous emission over a bandwidth around some center frequency and for guiding and reflecting the light beam between a pair of mirrors bounding the active on respective ends thereof to create an emitted beam of laser light. The mirrors each have narrow, spaced reflective maxima with the spacing of the reflective maxima of respective ones of the mirrors being different whereby only one the reflective maxima of each of the mirrors can be in correspondence and thereby provide a low loss window at any time. The preferred mirrors each include a plurality of discontinuities to cause the narrow, spaced reflective maxima wherein the spacing of the discontinuities of one mirror is different from the spacing of the discontinuities of the other mirror so as to cause the wavelength spacing of the maxima to be different. Additionally, the preferred embodiment includes a vernier circuit operably connected to the mirrors for providing an electrical signal to the mirrors which will cause continuous tuning within a desired frequency band, an offset control circuit operably connected to the mirrors for providing a voltage signal to the mirrors which will shift the reflective maxima of the mirrors into alignment at a desired frequency mode, and a phase control circuit for adjusting the laser mode wavelength to be in correspondence with the low loss window.

摘要： Highly reproducible, optically flat mirror facets are created by contacting a predetermined area of the InGaAsP/InP heterostructure system with a chemical etchant for a time period sufficient to expose a substantially vertical crystallographic surface throughout the entire heterostructure system. Contact of the exposed surface with HCl causes a preferred crystallographic plane to be exposed as an optically flat mirror facet.

摘要： Grating resonators for surface acoustic waves or surface optical waves are coupled in cascade via a track changer external to the resonator cavities. At least one grating of each resonator is partially transmissive in the resonant band, allowing the interchange of energy therebetween via the track changer. The track changer is comprised of either two or three reflective racks angled such that the energy reflected therein propagates along zero-temperature-coefficient paths. The three-rack, three-bounce U-path filter used as a track changer minimizes resonant energy losses due to variations in reflected wave angles from their designed values.
