Laser oscillation with polysilane waveguide tunable external resonator

Laser oscillation with polysilane waveguide tunable external resonator was observed at 1537nm. The resonator consists of the polysilane single-mode waveguide and the Bragg grating on the core. 5.6 mW laser power was obtained with 70% Bragg reflection. The wavelength shift due to resonator temperature was measured as 0.096 nm/°C in the range of 30-70°C.
