LD-PD

Our PL-2200-IG-AR2-TO5 extended InGaAs photodiodes show good response from 900 to 2200 nm. They have an active area with 2 mm diameter and are delivered in a TO5 package. We also offer avalanche photodiode modules with a built-in preamplifier and high voltage supply.

LD-PD offers distributed feedback lasers with a wide many emission wavelengths, covering the range from 760 nm to 3390 nm.

LD-PD offers a wide range of laser diodes based on a single heterojunction (SH), double heterojunction (DH) or quantum well (QW) gain medium. We also offer variants like Fabry–Pérot lasers and distributed feedback lasers, including single-frequency versions. Many lasers have a butterfly package with integrated thermoelectric cooler, while others have a TO package.

LD-PD offers various position-sensitive detectors. For example, the PL-1700-IGA-QD1-TO is a InGaAs quadrant APD detector in a TO5 package with good spectral response from 1000 to 1700 nm, active area 4 × 1 mm and response time 1.5 ns.

LD-PD offers various semiconductor optical amplifiers for signal wavelengths from 840 nm to 1650 nm, as needed e.g. for cable TV installations.

LD-PD offers various superluminescent diodes with central wavelengths ranging from 670 nm to 1700 nm.

LD-PD offers various superluminescent diodes with central wavelengths ranging from 670 nm to 1700 nm. Also, we offer benchtop ultrabroad sources as lab devices for telecom applications with a fiber output, or as modules with remote RS232 control, covering the whole wavelength range 1250 nm from 1650 nm.

The PL-NL-852-A-A81-SA-PZT is a single-frequency FBG-stabilized tunable narrow linewidth laser diode emitting 10 mW around 852 nm with 1 MHz linewidth. It comes coupled to a HI780 fiber with FC-APC connector. A 14-pin butterfly package with TEC is also available.

The PL-LSLD-1550-A-A81-SA is a low-power single-mode laser emitting 5 mW at 1550 nm with 60 to 70 nm spectral width. It has an internal monitor photodiode and a thermoelectric cooler and is coupling to a single-mode fiber with FC/APC connector.
