FLD5F20CE-E

The Modulator Integrated DFB Laser (MI DFB Laser)FLD5F20CE-E  with Wavelength Locker has an electro-absorption modulator monolithically integrated with a conventional Distributed Feed-Back (DFB) laser. The modulation voltage is applied to the modulator section while the laser section operates CW allowing extremely low wavelength chirping. Extinction ratios of more that 10dB can be achieved with 2.6 Vp-p modulation. The MI laser is installed in a butterfly type package. The tuned wavelength can be locked onto the desired ITU-T grid channel via use of the included fabry-perot etalon. The FLD5F20CE-E incorporates a highly stable optical coupling system. The module includes an optical isolator, monitor photodiode, thermistor and a thermo-electric cooler.
