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.
