NISP final LED types and parameters.
| Channel | Manufacturer | Model | λpeak (nm) | FWHM (nm) | Output Power | Material |
|---|---|---|---|---|---|---|
| A | Epigap | EOLC-970-17 | 970 | 70 | 2 mW at 20 mA CW | GaAs |
| B | Epigap | EOLC-1200-17-1 | 1200 | 70 | 3.5 mW at 100 mA CW | InGaAsP/InP |
| C | Epigap | EOLC-1550-17-1 | 1550 | 130 | 2.5 mW at 100 mA CW | InGaAsP/InP |
| D | LMSNT | LMS18LED-C | 1845 | 100–200 | 0.7–1.1 mW at 200 mA Quasi-CW | GaInAsSb/AlGaAsSb |
| E | LMSNT | LMS20LED-C | 2045 | 150–250 | 0.8–1.2 mW at 200 mA Quasi-CW | GaInAsSb/AlGaAsSb |
Notes. Wavelength, width, and power output are given here for room temperature. Resulting values at cold operating temperatures are given in Table 2. Output power are representative values provided by the manufacturer at 100% ‘continuous wave’ duty cycle for the Epigap LEDs, and 50% duty cycle for LEDs D and E. LED A is made from a single material, LEDs B–E from two-material heterostructures.
