OSI Laser Diode, Inc.’s (LDI) 1300 nm edge-emitting LEDs (light-emitting diodes) feature stable power and spectral characteristics over temperature. LDI’s MOCVD-grown InGaAsP devices are aligned to either a singlemode or multimode optical fiber in a stable, 14-pin dual-in-line package (DIP). Two versions of the DIP are offered. The standard package with a long-horn flange is configured either with or without a thermistor and a Peltier-effect thermoelectric cooler (cooler package). A second uncooled, low-profile package without a flange is also available for applications where space is limited and temperature control is not required.
