摘要	A tunable laser includes a reflective silicon optical amplifier, RSOA (104) with a reflective end and an interface end and an array of narrow-band reflectors (118), which each have a different center wavelength. It also includes a silicon-photonic optical switch (116), having an input port and N output ports that are coupled to a different narrow-band reflector in the array of narrow-band reflectors. The tunable laser also includes an optical waveguide (107) coupled between the interface end of the RSOA and the input of the silicon- photonic optical switch. The frequency of this tunable laser can be tuned in discrete increments by selectively coupling the input port of the silicon-photonic optical switch to one of the N output ports, thereby causing the RSOA to form a lasing cavity with a selected narrow-band reflector coupled to the selected output port. The tunable laser also includes a laser output (110, 112) optically coupled to the lasing cavity.
其他摘要	可调谐激光器包括反射硅光学放大器，具有反射端和接口端的RSOA（104）以及窄带反射器阵列（118），每个窄带反射器具有不同的中心波长。它还包括硅光子光开关（116），具有输入端口和N个输出端口，其耦合到窄带反射器阵列中的不同窄带反射器。可调谐激光器还包括耦合在RSOA的接口端和硅光子光开关的输入之间的光波导（107）。通过选择性地将硅光子光开关的输入端口耦合到N个输出端口中的一个，可以以离散的增量调谐该可调谐激光器的频率，从而使RSOA形成具有选定的窄带反射器耦合的激光腔。到选定的输出端口。可调谐激光器还包括光学耦合到激光腔的激光输出（110,112）。
主权项	A tunable laser, comprising: a reflective silicon optical amplifier (RSOA) having a reflective end and an interface end; an array of N narrow-band reflectors, wherein each narrow-band reflector has a different center wavelength; a 1 x N silicon-photonic optical switch, having an input port and N output ports, wherein each output port is coupled to a different narrow-band reflector in the array of N narrow-band reflectors; an optical waveguide coupled between the interface end of the RSOA and the input of the 1 x N silicon-photonic optical switch; an adjustment mechanism that facilitates adjusting a frequency of the tunable laser in discrete increments by selectively coupling the input port of the 1 x N silicon-photonic optical switch to one of the N output ports, thereby causing the RSOA to form a lasing cavity with a selected narrow-band reflector coupled to the selected output port, wherein the lasing cavity has a wavelength that is determined by the center wavelength of the selected narrow-band reflector; and a laser output optically coupled to the lasing cavity.
