1,550nm Modulator Integrated DFB Laser FLD5F20NP FEATURES • Modulator Integrated DFB Laser Diode Module • CW operation of DFB laser section • Modulation voltage applied only to modulator section • High speed butterfly package with GPO connection • Built-in optical isolator, monitor photodiode, thermistor, and thermo-electric cooler APPLICATION This MI laser is intended for intermediate reach applications (≤40km) at 10Gb/s. DESCRIPTION The Modulator Integrated DFB Laser (MI DFB Laser) 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 than 10 dB can be achieved with 2.6 Vp-p modulation. The MI laser is installed in a butterfly type package. The module incorporates a highly stable optical coupling system. The module includes an optical isolator, monitor photodiode, thermistor and a thermo-electric cooler.
