We present ultraviolet InGaN superluminescent diodes fabricated in a “j-shape” waveguide geometry. Under CW operation at room temperatures, devices emit optical power up to 80 mW at 395 nm with no tendency for lasing. The chip length was 1.5 mm. Emitted optical power was very sensitive to the device temperature. This effect limited the maximum optical power obtained in CW operation. With better packaging scheme better performance in CW regime should be achieved.
