AI Article Synopsis
- A 2.5 Gb/s differential binary phase-shift keying (DPSK) transmitter is designed using direct phase modulation of a VCSEL laser with a wavelength of 1539.84 nm.
- The VCSEL has been evaluated through both static and dynamic methods to assess its performance.
- The proposed transmitter offers a -39.5 dBm sensitivity with a single photodiode heterodyne receiver, making it a cost-effective option for future access networks.
Article Abstract
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.
