摘要： An integrated optical circuit is formed in a silicon layer and supported on a substrate, and a portion of the silicon layer is substantially thermally isolated from the substrate by extending over a recess in the substrate, e.g. in the form of a bridge. Temperature control means are provided to control the temperature of the portion of the silicon layer or of a device provided thereon. A thermal expansion gap may be provided in the portion to accommodate thermal expansion of the portion relative to the substrate.

摘要： External Cavity Laser An external cavity laser comprising first and second feedback means with an optical gain medium (2) therebetween, one of the feedback means is provided by a grating (4) formed in a silicon waveguide and the other feedback means is provided by a reflective back facet (2B) of the optical gain medium (2). The output wavelength of the laser, at a given temperature, can thus be determined during its manufacture and the laser can be made by mass production techniques. The grating (4) may be thermally isolated to obviate the need for temperature control means (6) to control the temperature of the grating (4). An array of lasers may be provided on a single chip.
