External cavity laser |
| abstract |
(57) Abstract: An external cavity laser comprising first and second feedback means and an optical gain medium (2) between the first and second feedback means, wherein one of the feedback means is a grating (4) formed in a silicon waveguide. ) And the other feedback means comprises a reflective rear facet (2B) of the optical gain medium (2). The output wavelength of the laser at a given temperature can be determined during manufacture, and the laser can be manufactured by mass production techniques. The grid (4) may be thermally isolated to eliminate the need for temperature control means (6) for controlling the temperature of the grid (4). The laser array may be formed on a single chip. |
