Abstract:
|
A 2.5Gb/s DPSK transmitter based on direct phase modulation of a VCSEL using its own chirp is proposed. The VCSEL, which wavelength is 1539.84nm, has been characterized both static and dynamically. The sensitivity of a single photodiode heterodyne receiver using the proposed 2.5Gb/sVCSEL transmitter is -39.5dBm. Thus, this transmitter is an extremely cost-effective solution for future access networks. |
