Paper Abstract

Transverse mode stabilized AIGaInP visible light laser diodes are described and their high power operations are discussed. The laser structure applied for transverse mode stabilization is a ridge shape self-aligned structure, which is designed taking fabrication reproducibility into consideration. A very thin GaInP etching stopper layer is introduced in order to enable easy and accurate control of the dimensions of the self-aligned structure. Threshold current is about 30-50mA. Over 10mW output power is obtained for LDs with as-cleaved facets. Output power is limited by COD (catastrophic optical damage). COD power level under continuous-wave (cw) operation is estimated to be 1.4-1.7MW/cm2. After facet-coating, a stable fundamental mode operation, up to 20mw (cw), and maximum output power 31mW (cw), which is limited by COD, have been obtained. The lasing wavelength is 670nm.
