DATA SHEET 10GBPS 850NM VCSEL ARRAYS V850-2106-001, V850-TBD-001 FEATURES: 850nm isolated cathode and anode VCSEL array Capable of 10Gbps per channel modulation Capable of flip chip mounting The V850-2106-001 and the V850-TBD-001 are high-performance 850 nm VCSEL (Vertical Cavity Surface-Emitting Laser) array die optimized for highspeed data communications. The array die are ideal for use in manufacturing transceivers for parallel optical interconnects. The arrays are available in either 4 or 12 channel configurations. Each device is a high radiance VCSEL designed to convert electrical current into optical power that can be used in fiber optic communications and other applications. As the current varies above threshold, the light intensity increases proportionally. The V850-2106-001 and the V850-TBD-001are designed to be used with inexpensive silicon or gallium arsenide detectors, but excellent performance can also be achieved with some indium gallium arsenide detectors. The low drive current requirement makes direct drive from PECL (Positive Emitter Coupled Logic) or ECL (Emitter Coupled Logic) gates possible and eases driver design. Designed to interface with 50/125 and 62.5/125um multimode fiber, the VCSELs produce circularly symmetric, non-astigmatic, narrow divergence beams that, with appropriate lensing, fiber couple all of the emitter power. The dual top side contacts provide a minimum 1um Au for ease of wire bonding. Wire bonding should be done with minimal pressure to ensure the VCSEL is not damaged. The die must be mounted using thermally conductive media. The VCSEL arrays are shipped on medium tack blue tape in 6 inch grip rings.

Reverse Power Supply Voltage 5V Continuous Forward Current 12mA ESD exposure (Human body model) 200V NOTICE: Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. 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. The inherent design of this component causes it to be sensitive to electrostatic discharge (ESD).

For the purpose of these tests, IF is DC current. 3. Threshold current varies as (TA – T0)2. It may either increase or decrease with temperature, depending upon relationship of TA to T0. The magnitude of the change is proportional to the threshold at T0. 4. Slope efficiency is defined as ΔPO/ΔIF. 5. To compute the value of Slope Efficiency at a temperature T, use the following equation: 7. Rise and fall times specifications are the 20% - 80%. Most of the devices will measure <135ps fall time. Rise and fall times are sensitive to drive electronics. 8. To compute the value of Series Resistance at a temperature T, use the following equation: RS(T) ≈ RS(25oC)*[1+ΔRS/ΔT)*(T-25)] 9. Beam divergence is defined as the total included angle between the 1/e2 intensity points. η(T) ≈ η(25oC)*[1+(Δη/ΔT)*(T-25)] 6. Rollover is the power at which a further current increase does not result in a power increase. TYPICAL PERFORMANCE CURVES Emitted Power vs. Current: Power varies approximately linearly with current above threshold. Threshold Current vs. Temperature: Threshold current varies parabolically with temperature; thus it can be nearly constant for a limited temperature range.
