Article: Performance Evaluation of Digital Coherent Receivers for Phase-Modulated Radio-Over-Fiber Links
Conference Paper: Millimeter-wave 6 Gb/s wireless BPSK electrooptic link[Show abstract] [Hide abstract] ABSTRACT: We demonstrate a technique for electrooptically upconverting and phase modulating digital data onto an RF carrier and performing coherent detection and downconversion of the received millimeter-wave signal to baseband. The binary phase-shift keyed RF signal is transmitted wirelessly to show its potential in wireless applications.
- [Show abstract] [Hide abstract] ABSTRACT: We evaluated the single side-band phase noise of a 40 GHz beat signal generated by two free-running lasers. This allowed us to verify the utility of the two free-running lasers is verified as a light source for a next-generation radio-over-fiber system using frequency such as those in the millimeter-wave and terahertz bands. We also measured the phase noise of a frequency quadrupler using a Mach-Zehnder modulator for comparison. The phase noise of the two free-running lasers and the frequency quadrupler are - 63.85 and -95.22 dBc/Hz at a 10 kHz offset frequency, respectively.

- [Show abstract] [Hide abstract] ABSTRACT: We propose and present a cost effective and simple technique of simultaneous generation and propagation of millimeter wave with recently standardized 10 giga bit passive optical network (GPON) by mixing of 2.5 Gbit/s, 30 GHz radio wave with 10 Gbit/s based band signal and then modulated by single Mach Zehnder modulator (MZM). In this scheme, we have applied 1490 nm for downstream, 1310 nm for upstream transmission and ON OFF keying (OOK) modulation format to make it fully align with existing standards and infrastructure. Simulation results show error free transmission performance with negligible power penalty over 25 km bidirectional fiber. We also highlight the principles and discuss the main technical challenges for commercial realization of 60 GHz spectrum.
