Value adding solutions to optical applicationsML-C-1550-FP-2G5-D11550 nm Fabry-Pérot Laser Diode Chip for 2.5 Gb/sDescription1550 nm laser chip with Modulight’s proprietary design. Theexcellent high temperature behavior of the chip makes it suitablefor uncooled transmitters and transceivers up to 2.5 Gb/s. Theproducts are shipped as bare dies.Features• Excellent high temperature performance• MQW active layer• Stable single transverse mode emissionApplications• SONET/SDH transmitters and transceivers• ATM links• Datacom transceivers• Fiber-in-the-loop• Measurement and instrumentationBare die productsElectro-Optical CharacteristicsParameter Symbol Min Typ Max Unit Test Condition1Rated optical power Po 5 - - mW -40-85°CThreshold current Ith - 9 14 mA 25°C- 23 35 85°COperating current Iop - 27 30 mA 25°C, Po=5 mW- 48 60 85°C, Po=5 mWOperating voltage Vop - 1.1 1.4 V 25°C, Po=5 mWSlope efficiency η 0.22 0.29 - W/A 25°C, Po=5 mW, 1-7 mW0.14 0.19 - 85°C, Po=5 mW, 1-7 mWCentral wavelength λc 1530 1550 1570 nm 25°C, Po=5 mW1485 - 1610 -40-85°C, Po=5 mWSpectral width (FWHM) 2 ∆λ - 1.3 2.5 nm 25°C, Po=5 mWSerial resistance RS - 8 - Ω 25°C, Po=5 mW, 1-7 mWTemperature shift of wavelength ∂λ/∂T - 0.65 - nm/K -40-85°C, Po=5 mWPerpendicular beam divergence angle θ⊥ 30 44 50 deg 25°C, Po=5 mWParallel beam divergence angle θ|| 18 23 35 deg 25°C, Po=5 mWModulation bandwidth 3 f-3dB 6 - - GHz 25°C, Iop=Ith+16 mA4 - - 85°C, Iop=Ith+16 mANote 1: All temperatures refer to heatsink temperatureNote 2: -20 dB noise floorNote 3: Chip-on-carrier, ground-signal-ground microwave probe41
