Abstract
A large‐optical‐cavity injection laser with low‐loss distributed Bragg reflectors has been realized. The temperature dependence of threshold current and of lasing wavelength clearly showed the DBR mode of operation. At room temperature, the lowest threshold current density thus far achieved was 7 kA/cm2. A coupling coefficient of around 50 cm−1 was estimated from the spectral bandwidth and from the intensity distribution of light scattered from the DBR region.Keywords
