TL;DR: A flexible two-way PM-based fiber-FSO convergence system employing one optical carrier transmission scheme and vertical cavity surface emitting laser (VCSEL)-based tunable optical band-pass filter (TOBPF) would be very attractive for the integration of fiber backbone and indoor networks to provide data signal flexibly.
Abstract: This paper aims to propose and conduct a practical demonstration of a flexible two-way phase modulation (PM)-based fiber-free-space optical (FSO) convergence system employing one optical carrier transmission scheme and vertical cavity surface emitting laser (VCSEL)-based tunable optical band-pass filter (TOBPF). One optical carrier is delivered to efficaciously reduce the dispersion effect caused by a 40-km single-mode fiber (SMF) transportation and the distortion caused by beating among multiple optical sidebands. Using a VCSEL-based TOBPF at the receiving site, the selected optical signal will be acquired flexibly from one of the multiple injected optical signals. This is the first time that an optical carrier transmission scheme and a VCSEL-based TOBPF are used in a two-way PM-based fiber-FSO convergence system. The downstream light is flexibly phase-remodulated with microwave/millimeter-wave data signal for uplink delivery. In-depth observation shows that bit error rate performs brilliantly via a 40-km SMF transportation with a 100-m FSO link. Such a flexible two-way PM-based fiber-FSO convergence system would be very attractive for the integration of fiber backbone and indoor networks to provide data signal flexibly.

TL;DR: In this article, a broadband class-AB (CAB) microwave-photonic link is demonstrated using an AlGaAs-GaAs electrooptic mode-converter-based polarization modulator (PolM).
Abstract: A novel broadband class-AB (CAB) microwave-photonic link is demonstrated using an AlGaAs-GaAs electrooptic mode-converter-based polarization modulator (PolM). The polarization-modulated signal is split into two paths, each independently optically biased to provide two electrooptic transfer functions operating close to, but on opposing sides of, their nulls. Experimental results at 2 and 4 GHz confirm that detection of the transfer functions in a differential detector provides excellent cancellation of second-order distortion and recreates the same third-order distortion as a quadrature-biased Mach-Zehnder modulator. Biasing the operating points near the null reduces optical carrier power, and hence, carrier-related noise, thereby increasing achievable spur-free dynamic range. The use of the PolM allows the CAB link to be implemented with a single modulator, reducing the matching requirements of dual modulator schemes and allowing third-order distortion-limited broadband operation.

TL;DR: In this article, the authors present a methodology for the incorporation of actively configurable interference-based optical elements into a circuit-level optoelectronic simulator based on modified nodal analysis.
Abstract: This paper presents a methodology for the incorporation of actively configurable interference-based optical elements into a circuit-level optoelectronic simulator. The self-consistent optoelectronic simulator is based on modified nodal analysis. The paper uses ring-resonator-based devices as examples of configurable devices. Construction of compact models of these devices from optical scattering and the waveguide elements using fundamental principles is presented in detail. In the results section, accuracy of the compact model of the ring resonator is first confirmed for static devices for steady-state and transient conditions. Last, the devices are placed in a complex optical circuit and used to modulate an optical carrier and select a particular channel from a multichannel optical signal. The modelling framework proposed proved to be robust and efficient for transient simulation of configurable elements in a self-consistent optoelectronic simulation engine.

TL;DR: In this paper, the influence of the residual data carried on the optical carrier is studied in three kinds of upstream transmissions based on wavelength-seeded reflective semiconductor optical amplifiers (RSOAs) for carrier-reuse wavelength-division-multiplexed-passive optical networks (WDM-PONs).
Abstract: We mathematically analyze and experimentally investigate the characteristics of subcarrier-modulated (SCM) light. Our investigation shows that the baseband data are also carried on the optical carrier after subcarrier modulation. This residual data introduce crosstalk when the optical carrier is separated from subcarriers and reused for uplink data modulation. The influence of the residual data carried on the optical carrier is studied in three kinds of upstream transmissions based on wavelength-seeded reflective semiconductor optical amplifiers (RSOAs) for carrier-reuse wavelength-division-multiplexed-passive optical networks (WDM-PONs). Results show that the crosstalk can be significantly suppressed with proper selection of the seeding power and operation conditions of downlink Mach-Zehnder modulator (MZM), including driving voltage and bias voltage.
