Abstract
Double heterostructure waveguides with contiguous regions of varying composition and dimension in the guiding layer have been grown by a modification of conventional liquid‐phase epitaxial growth procedures. This permits integration of active (lasers) and passive (modulators) optical components. Modulation of the laser intensity and envelope spectrum have been observed with a reverse bias applied to an intracavity modulator section. Low‐threshold lasers have been fabricated with far‐field radiation angles reduced by close to a factor of 3 over those in conventionally grown lasers.Keywords
