Ridge waveguide laser diodes al 1.55μm wavelength ale described in this paper. LDs have been obtained by LPE technology with CW threshold of 100 mA al room temperature
and the single transverse mode operation of 5 mW. The spectral line width of the LDs is less than 2?. The rise lime for impulse response of the LDs is about 100 picoseconds. Factors affecting the Jth
such as the thickness d and doping level of active layer and so on
are analyzed. The relation of output mode of the LDs to device structure is also discussed.
