1550nm DFB Fiber Coupled Butterfly Laser Diode Manufacturers

2mm Active Area TO-CAN InGaAs PIN Photodiode,high sensitivity photo-diode for use in infrared instrumentation and sensing applications. High spectral response in the region 800 nm to 1700 nm.

This 1270nm 5mW TO-CAN DFB Laser Diode is a product operable over a broad temperature range with a low temperature-wavelength coefficient. It is well suited for applications such as communications research, interferometry, and optical reflectometry for distance measurement in fiber or free space. Each device undergoes testing and burn-in. This laser comes packaged in a 5.6 mm TO Can. It contains an integrated aspheric focusing lens in the cap, allowing the focus spot and numerical aperture (NA) to be matched to SMF-28e+ fiber.

The 980nm pump laser utilizes a planar construction with chip on subcarrier. The high power chip is hermetically sealed in a epoxy-free and flux-free 14-pin butterfly package and fitted with a thermistor, thermoelectric cooler, and monitor diode. The 980nm pump laser uses FBG stabilization to "lock” the emission wavelength. It provides a noise-free narrow band spectrum, even under changes in temperature, drive current, and optical feedback. It is a light source for a fiber amplifier used in optical communication networks. The main types of optical fiber amplifiers are EDFA and FRA.

The 1330nm DFB built in TEC Butterfly Laser Diode is designed for broadcast and narrowcast analogue transmission in CATV and CWDM applications. The modules provide high output power while maintaining high linearity. The modules are housed in an industry standard hermetically sealed 14-pin butterfly package, which contains optical isolator, thermoelectric cooler, and power monitor photodiode.

The High Power C-band 10W 40dBm EDFA Fiber Optical Amplifier Module (EYDFA-HP) is based on the double-clad erbium-doped fiber amplifier technology, using a unique optical packaging process, coupled with a reliable high-power laser protection design, to achieve high-power laser output in the 1540~1565nm wavelength range. With high power and low noise, it can be used in fiber optic communication, Lidar, etc.

BoxOptronics Panda Polarization Maintaining PM Erbium Doped Fiber is mainly used in 1.5μm polarization-maintaining optical amplifiers, lidar, and eye-safe laser products. Polarization maintaining erbium doped fiber has high birefringence and excellent polarization maintaining characteristics. The fiber has a higher doping concentration, which reduces the required pump power and fiber length, thereby reducing the impact of nonlinear effects. At the same time, the optical fiber shows low splicing loss and strong bending resistance. Based on the optical fiber preparation process of BoxOptronics Laser, the polarization-maintaining erbium-doped optical fiber has good consistency.
