Electrically injected 1.55 ÎŒm InP-based photonic crystal microcavity coherent light source

Microcavities with dimensions on the wavelength scale are being extensively investigated due to their ability to exhibit enhanced spontaneous emission, directional output and single-mode operation. Photonic crystals with single or multiple defects have emerged as the preferred way to obtain such microcavities. We have designed and fabricated a 1.55 ÎŒm electrically injected photonic crystal surface-emitting microcavity device using an ImP-based heterostructure. The emission wavelength at 1.55 ÎŒm is an important wavelength for long haul optical communication applications.
