  • Abstract
    Double-heterostructure lasers with crescent-shaped InGaAsP active layers have been fabricated with CW emission of 1.54 ¿m. Lowest CW thresholds are 45¿47 mA for a 200 ¿m long cavity at 25°C. The lasing near-field widths are 2.5¿3.0 ¿m and the spectral widths to 10% of peak are 4¿5 nm under both CW conditions and modulation up to 320 Mbit/s.
