808 nm Cavity Surface Grating Semiconductor Laser by Holographic Lithography
The laser holography photolithography technology was designed
the optical path of holography lithography system was calculated and built based on the designed parameters of cavity grating
and the holography lithography conditions were optimized to fabricate the mask patterns of cavity grating. Based on the design of facet coating films
the facet coating process was investigated by precisely controlling the thickness and uniformity of films to realize the transmissivity
reflectivity
and bandwidth satisfied with the single longitudinal mode output of 808 nm facet grating LD. The single chip device of 808 nm facet grating LD was fabricated and characterized
with width of 100 m and length of 2 mm. High performance was achieved with central wavelength of 807.32 nm
FWHM of 0.36 nm
wavelength drift coefficient with temperature variation(15~45℃) of 0.072 nm/℃
maximum output power of 2.8 W
threshold of 0.49 A
and slop efficient of 1.05 W/A.
