Patent
All-optical 2R regenerator using self-seeded laser diode
TL;DR: In this paper, a self-seeded laser diode was proposed, which obtains a gain by itself without using expansive erbium-doped fiber amplifiers, thus, the cost is reduced and the system is simplified.
Patent
Quadrature amplitude modulation symbol mapping
TL;DR: In this paper, the constellation map is made up from each successive two bits of the input data bits successively identifying a quadrant within the quadrant until a group of bits is uniquely mapped to a single symbol.
Proceedings ArticleDOI
Demonstration of a symmetric bidirectional 60-GHz radio-over-fiber transport system at 2.5-Gb/s over a single 25-km SMF-28
TL;DR: In this paper, the first demonstration of a 60 GHz radio-over-fiber system simultaneously transmitting 2.5-Gb/s data for both directions over a single span of 25-km SMF-28.
Patent
Optical communication based on polarization dependent coherent optical nyquist frequency division multiplexing
TL;DR: In this article, a dual-polarized optical Nyquist frequency domain multiplexed signal is transmitted by an optical transmitter and an optical receiver, each component comprises multiple subchannels, possibly having different subchannel bandwidths and different modulation schemes.
Proceedings ArticleDOI
A novel carrier-eliminated optical millimeter-wave generation using a single over-driven phase modulator
TL;DR: In this paper, a carrier-eliminated 40GHz optical mm-wave generated by over-driving a phase modulator is proposed for error-free transmission over 10-km SMF-28 and 3-m wireless.
