摘要:
Data are presented on vertical-cavity surface-emitting lasers (VCSEL's) that use high-index half-wave GaAs spacer layers and electronic tunnel injection and confinement. To our knowledge, this is the first demonstration of tunnel injection in a vertical-cavity laser, Threshold currents range from 344 mu A for a 6.5-mu m diameter device to 151 mu A for a 1-mu m diameter device, The relatively high threshold currents are attributed to a detuned cavity and higher order transverse-mode operation.
