It is found that optimization of the structure parameters of ridge waveguide (RWG) can decrease the threshold current of RWG laser diode. The way to get the device with sub micron ridge width is proposed. In order to improve the controllability of the dry etching depth during the fabrication process of ridge waveguide, an etch stop layer is designed in the vertical structure of GaInP/AlGaInP ridge waveguide.
