The rack contains control and measurement electronics, test fixtures, and uninterruptible power supply (UPS). The (64) Quad Output 8515Q Laser Diode Driver (LDD) modules in the (4) Newport 9016 Modular Controllers provide 256-Channels @ 1.5 A of current and a compliance voltage of up to 5 V. Both Constant Power (APC) and Constant Current (ACC) modes are available. Constant power mode operation utilizes a large area silicon photodiode, which is part of the test fixture. Forward current, forward voltage, and optical power are all measured at a resolution of 16-bits. The (8) 8375 TEC modules in the (2) Newport 9008 Modular Controllers provide up to 7.5 A of current and power up to 60 W. The compliance voltage is 8 V. The temperature of each laser diode is measured and recorded for increased temperature accuracy. Newport's Modular Drawer Interface makes interchanging devices fast and effortless. These Modular Drawer laser diode fixtures can be designed to work with any package needed by the user. Newport can be contacted regarding purchasing new drawers to interface to this system, or a custom fixture can be designed by the end-user interfacing to the standard D-sub connectors. On the back side of each Drawer, there are (4) 26-pin and (2) 15-pin D-sub connectors. Of these, (4) connect to eight Quad 8515Q Laser Diode Driver Modules in the Model 9016 chassis (to drive the laser diodes), (1) connects to an 8375 TEC Driver Module in the Model 9008 chassis (to drive the TECs), and (1) connects to the Agilent 34970A (to take photodiode readings). This system is currently configured to hold COS (Chip on Submount) laser diodes. The (16) Modular, Removable Drawers are designed to hold laser diodes for the purpose of burn-in. Spring loaded "pogo pins" secure each chip-on-submount device to a temperature-controlled plate and provide electrical connection with the anode and cathode contact pads. These fixtures hold up to sixteen laser diodes. Each fixture has two peltier coolers to control the plate temperature. A large area silicon photodiode measures the optical output of each laser diode. Each photodiode is angled 8 degrees to prevent back reflections to the laser diode. An uninterruptible power supply is supplied to act as a continuous voltage regulator and transient suppressor. In the event of power failure, the UPS switches to battery backup power and notifies the computer. ## Images - - - - -
