2 2 lucent technologies inc. d2570, d2526g, d2555 wavelength-selected data sheet direct modulated isolated dfb laser module august 2000 description (continued) controlled feedback the module contains an internal optical isolator that suppresses optical feedback in laser-based, ?ber-optic systems. light re?ected back to the laser is attenuated a minimum of 30 db. controlled temperature an integral thermoelectric cooler (tec) provides stable thermal characteristics. the tec allows for heating and cooling of the laser chip to maintain a temperature of 25 c for case temperatures from C40 c to +70 c. the laser temperature is monitored by the internal thermistor, which can be used with external circuitry to control the laser chip temperature. controlled power an internal, ingaas, pin photodiode functions as the back-facet monitor. the photodiode monitors emission from the rear facet of the laser and, when used in con- junction with control circuitry, can control optical power launched into the ?ber. normally, this con?guration is used in a feedback arrangement to maintain consistent laser output power. standard package the laser module is fabricated in a 14-pin, hermetic, metal/ceramic butter?y package that incorporates a bias tee, which separates the dc-bias path from the rf input. the rf input has a nominal 25 w impedance. the laser module is equipped with corning smf-28 type ?ber. the ?ber has a 900 m m tight buffer jacket. various connectors and pigtail lengths are available. lucent technologies microelectronics groups opto- electronic components are being quali?ed to rigorous internal standards that are consistent with telcordia technologies tr-nwt-000468. all design and manu- facturing operations are iso * 9001 certi?ed. the mod- ule is being fully quali?ed for central of?ce applications. * iso is a registered trademark of the international organization for standardization. pin information ? a positive current through the thermoelectric heat pump cools the laser. ? both leads should be grounded for optimum performance. top view. figure 1. circuit schematic pin name 1 thermistor 2 thermistor 3 laser dc bias (cathode) (C) 4 back-facet monitor anode (C) 5 back-facet monitor cathode (+) 6 thermoelectric cooler (+) ? 7 thermoelectric cooler (C) ? 8 case ground 9 case ground 10 case ground 11 laser anode (+) ? 12 rf laser input cathode (C) 13 laser anode (+) ? 14 case ground 1-567 tec l1 160 nh isolator r1 20 w package grounds ?+ ++ 765 4 32 1 8 9 10 11 12 13 th 10 k w 14

(12.7 mm x 30 mm) in size. the surface ?nish of the heat sink should be better than 32 m in. (0.8 m m), and the surface ?at- ness must be better than 0.001 in. (25.4 m m). using thermal conductive grease is optional; however, thermal performance can be improved by up to 5% if conductive grease is applied between the bottom ?ange and the heat sink. 2. mount four #2-56 screws with fillister heads (m2-3 mm) at the four screw hole locations (see outline diagram). the fillister head diameter must not exceed 0.140 in. (3.55 mm). do not apply more than 1 in./lb. of torque to the screws. figure 2. fillister head screw parameter value unit human-body model >400 v 1-532 note: dimensions are in inches and (millimeters). 0.118 (3.00) 0.062 (1.58) 0.140 (3.56) 0.031 (0.79) 0.129 (3.28) r 0.086 (2.18) 0.041 (1.04)
