Distributed Feedback (DFB) and Distributed Bragg Reflector (DBR) laser diodes feature a frequency-selective structure within the laser chip, which restricts the laser emission to a single longitudinal mode.
Serving North America, RPMC Lasers offers a wide selection of distributed feedback lasers (DFB), including single emitter laser diodes, laser diode modules, and quantum cascade lasers (QCLs). Available in NIR, SWIR, and LWIR wavelengths, these single-mode DFB laser diodes offer a mode-hop-free tunable, single-frequency output and are available ...
28 wrz 2023 · Thorlabs' Distributed Feedback (DFB) Lasers are narrow-linewidth, single-frequency laser diodes that use a corrugated waveguide throughout the active region of the laser cavity (see SFL Guide tab). A DFB laser's periodic structure acts as a distributed reflector, providing optical feedback and wavelength selection for the diode.
The SCW 1731F-D40R laser diode module is a 1650 nm Al RWG DFB laser diode packaged in a 14 pin DIL package. The laser diode is optically coupled to an SMF fiber pigtail and includes a thermoelectric cooler and an electrically isolated temperature sensing thermistor.
The DFB-1310-10LR-LCA is specifically designed for applications based on several optical communications standards, including IEEE 10GBASE-LR, STM64, STM64 FEC, 10GFC, 10G GbE, 10G GbE FEC, & 10GFC FEC.
Broadcom's 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 LDB-DFB-1550-50CW is a single frequency CW laser coupled with Polarization Maintaining fiber. Built with Distributed Feed-Back Grating (DFB) as cavity reflector, it provides a pure, single longitudinal mode, and extremely stable wavelength source. This laser diode is fabricated with Multiple Quantum Well (MQW) for excellent reliability and ...
