概要

We describe the fabrication method and characteristics of hybrid external cavity lasers composed of a spot-size converter integrated LD(SS-LD)and a UV written Bragg grating in a planar lightwave circuit(PLC) on a Si substrate. The SS-LD is passively aligned on a Si platform formed in the PLC, and the UV grating is created in the PLC with ArF laser irradiation through a phase mask. This structure enables us to fabricate a stable single-mode laser with a precisely controllable oscillation wavelength. By using the above techniques, we obtained a threshold current of 7-8mA and a side mode suppression of 37dB for an external cavity laser operating at 1.3μm. Moreover, we successfully demonstrated a four-channel external cavity laser with a wavelength interval of 2nm±0.1nm by integrating 4 SS-LDs on a PLC and controlling the Bragg wavelengths with ArF laser irradiation without a phase mask.
