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