Abstract :
To decrease the operational power consumption of a laser module, a lateral-grating-assisted lateral co-directional coupler (LGLC) tunable laser with a high-mesa buried heterostructure (BH) was fabricated. The LGLC laser demonstrated successful tunable laser operation in the C-band wavelength range of 37 nm with 40 mA injection current into an LGLC filter at 50°C.
