Distributed Feedback (DFB)

Distributed Feedback (DFB) Lasers Overview

Distributed Feedback (DFB) Laser Diodes are single frequency and offer a Narrow Linewidth with good side mode suppression. A Bragg grating is utilized to ensure single frequency emission.

Discreet-Mode (DM) Laser Diodes offer very similar performance to DFB Lasers. Discreet-Mode (DM) Laser Diodes are produced with a simple and low-cost fabrication process and have many advantages, such as very high side mode suppression ratio, stable operation over a broad temperature range, narrow linewidth and low sensitivity to optical feedback.

Free space and fiber pigtailed versions are available in these IR narrow linewidth lasers.

We offer a wide range of wavelengths and output powers to choose from in our DFB Lasers.  Contact RPMC for a quote or more information.

EP Series

The EP series includes tunable single-frequency (DFB-like) diode lasers and Fabry-Perot laser diodes in wavelengths from 1270nm thru 2350nm for communications, sensing and measurement applications. They are enabling new volume markets through the mass deployment of disruptive technologies.

All single mode diode lasers exhibit superior linewidth properties across the entire wavelength range when compared to typical DFB lasers. Utilizing a proprietary discrete-mode (DM) technology ensures excellent side mode suppression ratio (SMSR), without the mode hops inherent to most distributed feedback (DFB) lasers.

The EP Series is specifically engineered for applications such as gas sensing, LIDAR, metrology, and optical communications. Multiple packaging options are available including the Fiber coupled 14-pin butterfly, TO39 (w/TEC), and TO56.

For a complete module incorporating the fiber coupled butterfly package with an integrated current driver and TEC controller, designed for ease of operation, it is the ideal platform for high stability gas detection or remote sensing.  See the DX1 Series.

QCL Series

mirSense Product Family

The QCL series is a high power pulsed Quantum Cascade Laser based on proprietary technology which incorporates high-powered diodes (typically watt-level) emitting in the main transmission bands of the atmosphere (4.0µm, 4.6µm, 4.8µm, 9.x µm). The ITAR free MirSense technology exhibits outstanding performance in terms of power and wall-plug efficiency. This high-performance QCL laser assembly takes full advantage of MirSense’s state of the art technologies.
