摘要: The present applicants have discovered that one can make a surface emitting laser with enhanced optical confinement and improved heat sinking characteristics by etching away portions of the growth layers peripheral to intended cavity regrowing regions material having lower index refraction than active region. Using low damage either in situ regrowth or hydrogen plasma cleaning followed regrowth, isolation be made.
