Summary :

This paper presents a surface emitting injection laser with improved short cavity structure operating at 1.30 µm (77 K) of wavelength. The selective etching technique has been applied to take out the InP substrate in order to reduce the absorption loss and resultant cavity length was 7 µm. The threshold was as low as 50 mA at 77 K. The device operated up to 140 K with one single longitudinal mode and small wavelength change (0.64 /degree). The near-field diameter was 9 µm and the far-field angle (FWHM) was 9 degrees. The polarization was linear.
