Thermally tunable integrated planar Bragg-grating stabilized diode laser
Thermally tunable integrated planar Bragg-grating stabilized diode laser
A pair of external cavity diode lasers are fabricated using an integrated planar Bragg grating. The planar waveguide and Bragg reflector is UV-written within a glass-on-silicon chip. Intensity isolated, continuous wavelength tuning at > 1kHz modulation rate is achieved using micro-heating elements fabricated directly over the Bragg grating. Low RIN (<140dB) and low linewidth (δν ∼ 200 kHz) operation is found using a heterodyne measurement. We demonstrate the lasers operating in phase-locked loop configuration where one laser is frequency-offset locked to the other.

Abstract
A pair of external cavity diode lasers are fabricated using an integrated planar Bragg grating. The planar waveguide and Bragg reflector is UV-written within a glass-on-silicon chip. Intensity isolated, continuous wavelength tuning at > 1kHz modulation rate is achieved using micro-heating elements fabricated directly over the Bragg grating. Low RIN (<140dB) and low linewidth (δν ∼ 200 kHz) operation is found using a heterodyne measurement. We demonstrate the lasers operating in phase-locked loop configuration where one laser is frequency-offset locked to the other.
