DATA SHEET VCSEL SENSOR FLAT WINDOW TO CAN SV3637-001 FEATURES: Designed for low drive currents between 7 and 15mA Flat Window TO-46 style package High speed 1 Ghz The SV3637 combines many of the desired features of an LED and the advantages of a laser diode. The VCSEL provides increased power output at low drive currents. As the current increases above its threshold, the light intensity increases proportionally. Custom packaging designs are also available. The different packages are for different applications both in the datacom market as well as in the sensor market.

This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operations section for extended periods of time may affect reliability. NOTICE: The inherent design of this component causes it to be sensitive to electrostatic discharge (ESD). To prevent ESD-induced damage and/or degradation to equipment, take normal ESD precautions when handling this product SV3637-001 VCSEL ELECTRO-OPTICAL CHARACTERISTICS VCSEL Parameters Optical Power Output Threshold Current Threshold Current Temperature Variation Slope Efficiency Test Condition I F =12mA o o T A = 0 C to 70 C Po =1.3mW o o Slope Efficiency Temperature variation Peak Wavelength T A = 0 C to 70 C P Temperature Variation Spectral Bandwidth, RMS I F =12mA I F =12mA Laser Forward Voltage Series Resistance Beam Divergence I F =12 mA I F =12 mA I F =12 mA I F =12mA Symbol Po I TH I TH Min. 1.5 -1.9 7 1.9 830 850 1.75 25 10 VCSEL ELECTRO-OPTICAL CHARACTERISTICS (TA=25 oC unless otherwise stated) Notes 2 mW/mA 4 3 %/ C 870 nm nm/oC 0.06 1.5 15 Units mW mA mA o -0.5 P/T VF RS Max. 0.3 /T P Typ. 1.5 3.5 0.85 nm 2.2 40 V Ohms deg 5 SV3637-001 VCSEL SENSOR FLAT WINDOW TO CAN NOTES 1. 2. Reliability is a function of temperature, see www.finisar.com/aoc.php for details. For the purpose of these tests, IF is DC current. 4. Slope efficiency is defined as PO/IF. 5. Beam divergence is defined as the total included angle between the half intensity points. 3.. Threshold current varies as (TA - TO)2. It may either increase or decrease with temperature, depending upon relationship of TA to TO. The magnitude of the change is proportional to the threshold at TO. TYPICAL PERFORMANCE CURVES Pmax Emitted Power Typical operating current / power I th Current Threshold Current vs. Temperature: Threshold current varies parabolically with temperature; thus it can be nearly constant for a limited temperature range. Threshold Current Emitted Power vs. Current: Power varies approximately linearly with current above threshold.
