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
