ECCW Narrow Linewidth CW External Cavity

Laser Diode

The ECCW series external cavity laser is a cost effective solution for a

coherent laser source. The laser is fabricated in a 14-pin hermetically

sealed butterfly package that incorporates a bias tee circuit, an

integrated thermoelectric cooler (TEC), a thermistor, and a back facet

monitor photodiode. The ECCW provides substantially lower phase

noise and a longer coherence length than other semiconductor lasers,

including DFB lasers. The wavelength stability is assured by design,

eliminating the need for wavelength lockers and complex feedback

control circuits.

Absolute Maximum Ratings1

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are

absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in

excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for

extended periods can adversely affect device reliability.

1. Absolute maximum data are limited to system design only; proper device performance is not guaranteed over rating listed above. Operation

beyond these maximum conditions may degrade device performance, lead to device failure, shorter lifetime, and will invalidate the device

warranty.

2. TEC current should not exceed 2.0 A during turn on, and case temperature under any conditions should not change faster than 10oC/min.

3. Soldering iron only; no reflow or dip soldering allowed.

4. See mounting recommendations below.

Reliability/Quality

Designed to meet qualification requirements of TelcordiaTM (Bellcore) GR-468-CORE.

Handling and Mounting

1. The Laser should be mounted on a heat sink at least 13 x 35 mm in size with surface finish better than 1 μm

and flatness better than 25μm. It is recommended that the laser be mechanically mounted to the heat sink

using M2-3 mm (#2-56) screws. Apply torque 0.1-0.11 m*N (0.8-1 lb*in). It is also recommended to use

thermally conductive grease between the laser package and heat sink.

2. The fiber pigtail must not be subject to a bend radius below 35mm.The fiber is unable to withstand

temperatures in excess of 120 ºC without degradation. Avoid high temperature contact during soldering
