We report the first long-haul DWDM transmission using three chirp-managed lasers spaced 50-GHz apart in SSMF at 10-Gb/s. Transmission penalties less than 0.7 dB over a dispersion-managed 1980-km link was measured with performance comparable to NRZ-OOK.
Summary form only given. We have proposed a novel receiver for dual-wavelength detection having an embedded fiber circuit with surface-mounted photodiodes (PDs). Using this technique, it is possible to make an in-line receiver device connected to a transmitting laser diode (LD) module, because the primary transmission media, the fiber, remains intact through the receiver module. We demonstrate a unique...
A four-channel DBR laser array with different lasing wavelengths has been developed for a light source in WDM systems by using a simple selective MOCVD growth technique. Four different lasing wavelengths with a 5nm spacing were achieved by varying the waveguide thickness. The fabrication techniques and lasing characteristics of the device are demonstrated.<<ETX>>
