摘要： An integrated optical device formed in a semiconductor substrate incorporated an integral lens element in the substrate for providing focusing of the output beam. The device includes an optically active region for generating and confining optical radiation and having an output end for emitting an output beam from the optically active region; and a lens region adjacent the output end which has an increased band gap to the adjacent substrate material and is shaped to provide a lens effect on said output beam. The optically active region forms a cavity having a longitudinal axis, and the lens region extends along the longitudinal axis and has a lateral extent that varies as a function of distance along the longitudinal axis.

摘要： An optical system for producing an array of single transverse mode laser beam output includes a monolithic laser array (23) having a plurality of outputs (5) in which each laser (4) is adapted for operation so as to produce a single transverse mode output; and an array of waveguides (10), the waveguide array being positioned in relation to the laser array such that each laser output from the laser array couples into an input of a respective waveguide (11) in the waveguide array, the waveguide array maintaining the single transverse mode of each laser output at a respective waveguide output to provide a single transverse mode beam output. Multiple laser arrays (23) be coupled to a single waveguide array (10) enabling the formation of very large arrays and arrays with beam pitch smaller than otherwise possible.

摘要： A carrier for multiple monolithic semiconductor optical components facilitates precision mounting of the components so as to achieve a two-dimensional array of optical output beams. The carrier includes a first planar substrate region for positioning and supporting a first one of said optical components in a first plane and a second planar substrate region for positioning and supporting a second one of said optical component in a second plane different from the first plane. When optical components are mounted, a resulting device comprises a first and a second monolithic laser array, each monolithic laser array comprising a plurality of laser elements each extending generally in an x-z plane, the z-axis being defined substantially parallel to the optical axes of the laser elements. The first and second laser arrays are separated along the y-axis by being disposed on different regions of the carrier substrate in different x-z planes.

摘要： An active photonic semiconductor device, such as a laser, optical amplifier or LED, is monolithically integrated with a photodetector. The device includes an optically active region formed on a substrate including a first electrical contact for initiating emission of photons within the optically active region; an optical confinement structure generally defining a principal optical path through the device and through said optically active region; and a photodetector structure formed on the substrate including a second electrical contact displaced from and substantially electrically insulated from the first contact, overlying a part of the principal optical path, for receiving carriers generated by said emitted photons. The photodetector is preferably positioned to cover an intermixed / non-intermixed region close to a facet of the device and also close to the active region of the device. The photodetector is weakly coupled to the optical confinement structure such that a very small proportion of the optical radiation can be monitored without deleteriously affecting the performance of the device.

摘要： A method of performing quantum well intermixing in a semiconductor device structure uses a sacrificial part of a cap layer, that is removed after QWI processing, to restore the cap surface to a condition in which high performance contacts are still possible. The method includes: a) forming a layered quantum well structure including a doped cap layer; b) forming an etch stop layer over said cap layer; c) forming a sacrificial layer over said etch stop layer, said etch stop layer having a substantially lower etch rate than said sacrificial layer when exposed to predetermined etch conditions; d) carrying out a quantum well intermixing process on the device structure, which process induces significant damage to at least a portion of the sacrificial layer; e) removing the sacrificial layer in at least a contact region of the device using an etch procedure selective against the etch stop layer to expose said etch stop layer in the contact region; and f) forming a contact over the layered quantum well structure in at least said contact region.
