“…Light of such character is said to be linearly polarized, and maintains a constant direction of oscillation, and does vary spatially in a regular manner, producing either elliptically polarized or circularly polarized light (Fowles 1975;Jackson 1975;Pedrotti & Pedrotti 1987). Polarization characteristic have been used in radio transmission to reduce interference between channels, particularly at VHF frequencies and beyond (Masayoshi 2007;Yao et al 2007). Free-space communication has forced the use of circular polarization, which has the fundamental advantage of precluding disturbance from the reflections of signals (Leitch et al 2002;Elser et al 2009).…”

An all-optical two 2-bit numbers multiplication with the help of Semiconductor Optical Amplifier (SOA)-assisted Sagnac Switch is proposed and described. The paper describes the multiplication using a set of all-optical half-adder and AND gate. Because of the lack of fast, accurate, and large dynamic range analog-to-digital converter, optical implementation of the digital multiplication through analog convolution algorithm yields a slow digital multiplier. By using a set of optical half-adder and optical AND, a new optical fast digital multiplication method is proposed. The new method promises both higher processing speed and accuracy. Numerical simulation result confirming described methods and conclusion are given in this paper.

“…Through tuning PC 2 and PC 3 , the light wave from the LO laser source is co-polarized with the received optical signal. Note that in a practical system, PC 2 can be replaced by a dynamic PC, to accommodate the random polarization state of the input optical signal [16] . At the output of the coherent receiver two photocurrents are generated that are sampled by a digital storage oscilloscope (Agilent DSO-X 93204A) with a sampling rate of 80 GSa/s.…”

A 4 × 4 multiple-input multiple-output coherent microwave photonic (MWP) link to transmit four wireless signals with an identical microwave center frequency over a single optical wavelength based on optical independent sideband (OISB) modulation and optical orthogonal modulation with an improved spectral efficiency is proposed and experimentally demonstrated. At the transmitter, the OISB modulation and optical orthogonal modulation are implemented to generate an OISB signal using a dual-parallel Mach-Zehnder modulator (DP-MZM) driven by four microwave orthogonal frequency-division multiplexing (OFDM) signals with an identical microwave center frequency. At the receiver, the OISB signal is coherently detected at a coherent receiver where a free-running local oscillator (LO) laser source is employed. Digital signal processing is then used to recover the four OFDM signals, to eliminate the phase noise from the transmitter laser source and the LO laser source, and to cancel the unstable wavelength difference between the wavelengths of the transmitter laser source and the LO laser source. Error-free transmission of three 16 quadrature amplitude modulation (16-QAM) 1 Gbps OFDM signals and one 16-QAM 1.5 Gbps OFDM signal at a microwave center frequency of 2.91 GHz over a 10 km single-mode fiber is experimentally demonstrated.
