Abstract
Characteristics of low threshold, high-index contrast, 2-D InP slab triangular- and square-lattice photonic crystal band edge lasers operating near 1,550 nm are summarized. Surface-emitting lasing actions are observed near the third /spl Gamma/ points and the band edges. A very low threshold of 35 /spl mu/W is observed from the laser operating near the third TE-like mode /spl Gamma/ point. The lasing occurs from a very small pump area of 6 /spl mu/m in diameter.
