Buried transverse-junction stripe laser for optoelectronic-integrated circuits

Abstract
A buried transverse-junction stripe (TJS) laser, a suitable laser diode for integration, has been fabricated using molecular-beam epitaxial growth. The fundamental characteristics of the laser were as good as those of a conventional TJS laser. We have also demonstrated a fabrication process for the laser that is compatible with that for metal-semiconductor field-effect transistors (MESFETs) to be monolithically integrated. The characteristics of the MESFETs fabricated on substrates processed for the laser were the same as those fabricated on virgin substrates when such processed substrates were etched 2 μm deep.
