DFB Butterfly Lasers

Box Optronics Distributed Feedback DFB butterfly Lasers are narrow line width, single-frequency laser diodes that use a corrugated wave guide throughout the active region of the laser cavity, These DFB butterfly laser diodes are housed in 14-pin butterfly package. They include fiber pigtails from 1 to 1.5 m in length, terminated with FC/APC connectors. Each butterfly package laser diode includes a data sheet with operating data for the particular unit, These laser have been widely used in C/DWDM systems,Fiber optical sensors, Laser sources, CATV systems, LAN, WAN and metro networks, NH3,CH4 Gas detection.


Box Optronics provide many options in DFB butterfly laser diodes, we have 1270nm~1610nm 1310nm 1550nm CWDM 10mW 20mW DFB butterfly laser diode, 1528.77~1610.06nm DWDM band Center Wavelengths ITU wavelength 10mW 2mW DFB butterfly laser diode, 1392nm 1512nm 1533nm 1567nm 1653nm 10mW butterfly laser diode for gas detection.

DFB butterfly Laser’s periodic structure acts as a distributed reflector, providing optical feedback and wavelength selection for the diode. This allows these lasers to achieve a 2 MHz or 0.1nm typical line width with an excellent side mode suppression ratio (40 dB typical). These DFB lasers are designed for mode-hop-free, continuous current tuning from 15 °C to 35 °C. These diodes can be both temperature and current tuned to achieve the desired operating wavelength with typical output powers of 10mW~100mW for the CWDM, DWDM devices.
