# 247F-1xx
## High-Power, Edge-Emitting, DFB Laser Chip for Uncooled Applications up to 100mW
## Overview
The Broadcom® 247F-1xx is a single-mode, edge-emitting laser diode chip that emits at CWDM wavelengths for use in uncooled applications up to 100-mW output power. The design is a capped mesa buried hetero-structure (CMBH) grown on n-type substrate with multi-quantum well (MQW) active layers and a distributed-feedback (DFB) grating layer. The facets are coated with an anti-reflectance layer on the front facet and a high-reflectance coating on the rear facet. The design supports operation in non-hermetic environments. Gold bonding pads are provided on both the p and n sides. A hexadecimal number appears on both sides of the chip for identification purposes. All laser chips come from wafers that have been certified using a representative lot of devices that must achieve an acceptable yield for burn-in and the multi-temperature CW test. Each shipped bare die is pulse-tested at 25°C.
