摘要:

We report in this work a record low threshold (∼4 mA, cw), 1.55 &mgr;m wavelength, grating‐coupled surface‐emitting laser (GCSEL) which rivals all other existing SELs in the 1.3 or/and 1.55 &mgr;m regions. Methods to improve the asymmetric far‐field patterns and to obtain even lower threshold SELs are also demonstrated and/or suggested. ©1995 American Institute of Physics.
