Chirp-based direct phase modulation of VCSELs for cost-effective transceivers

A 2.5  Gb/s differential binary phase-shift keying (DPSK) transmitter based on direct phase modulation of a vertical cavity surface emitting lasers (VCSEL) using its own chirp is proposed. The VCSEL, which has a wavelength of 1539.84 nm, has been characterized both statically and dynamically. The se...

Description
Summary:A 2.5  Gb/s differential binary phase-shift keying (DPSK) transmitter based on direct phase modulation of a vertical cavity surface emitting lasers (VCSEL) using its own chirp is proposed. The VCSEL, which has a wavelength of 1539.84 nm, has been characterized both statically and dynamically. The sensitivity of a single photodiode heterodyne receiver using the proposed 2.5  Gb/s VCSEL transmitter is -39.5  dBm. Thus, this transmitter is an extremely cost-effective solution for future access networks.
