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
• Available at C-Band ITU-T grid wavelengths between 1529.55nm
thru 1563.05nm
APPLICATION
This MI DFB laser is intended for long reach applications (80km)
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.
