1550nm Superluminescent Chip on Submount >30mW

ALL Product Laser Chip 1550nm Superluminescent Chip on Submount >30mW


Description

The SLT-COS-SLD-1550-30 series is a broadband SLED that operates in a true inherent superluminescent mode. This 1550nm Superluminescent Chip on Submount superluminescent property generates broader band at higher drive currents in contrast to other conventional SLEDs which are ASE-based, where high drive tends to give narrower band. Its low coherence reduces Rayleigh backscattering noise. Coupled with high power and large spectral width, it offsets photoreceiver noise and improves spatial resolution (in OCT) and measurand sensitivity (in sensors). The SLED is available in Chip on submount package. It is compliance with the requirements of Bellcore Document GR-468-CORE.

*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.

**These maximum stresses are to be applied only after the chip is properly bonded to a heat sink. Applying current to a bare chip can damage the device.

ESD and EOS:

Switching transients can cause electrical overstress (EOS) damage in a chip.

EOS may result from improper ESD handling, improper power sequencing, a faulty power supply or an intermittent connection.

 

 Proper turn-on sequence:

a. All ground connections

b. Most negative supply

c. Most positive supply

d. All remaining connections

 Reverse order to turn-off.

Laser Safety:

Caution: Use of controls, adjustments and procedure other than those specified herein may result in hazardous laser radiation exposure.
