Abstract :
CW light output power as high as 38 mW at room temperature and with a CW operable temperature as high as 80°C, both under single-longitudinal-mode operation, has been achieved for the first time in newly developed 1.3 ¿m distributed-feedback (DFB) laser diodes with a double-channel planar buried heterostructure (DC-PBH).
