“…2(a), the electric fields E 1 and E 3 represent the electric fields before and after the coupling region in the waveguide, respectively, and E 2 and E 4 stand for the electric fields before and after the coupling region on the ring, respectively. When the resonator is at resonance, the relative intensity of the circulating light in the ring can be written in terms of α, R ring and γ as [19] ( ) …”

This paper reports a pure angular momentum generator using a ring resonator surrounded by a group of nano-rods. The evanescent waves of the circulating light in the ring are scattered by the nano-rods and generate a rotating electromagnetic field, which has only angular momentum but no linear momentum along the axis of rotation. The angular order is determined by the difference between the order of Whispering Gallery mode and the number of the rods, the rotating frequency is equal to the light frequency divided by the angular order. The maximum amplitude of the rotating electromagnetic fields can be 10 times higher than the amplitude of the input field when there are 36 rods (R rod = 120 nm, n r = 1.6). The pure angular momentum generator provides a new platform for trapping and rotation of small particles.

“…In recent years optical fiber couplers, such as 2 × 2 and 3 × 3 optical single-mode fiber couplers, with ring or loop configurations have attracted much attention [1][2][3][4][5]. The fiber ring laser using an erbium-doped-fiber amplifier (EDFA) can be designed as a multimode, single-mode, or pulsed operation [6][7][8][9][10][11][12][13].…”

In this article we propose two kinds of new fiber ring structure with a semiconductor optical amplifier. The first structure is a one-fiber-ring amplifier with an 8 × 8 fiber coupler and a semiconductor optical amplifier (SOA). The second fiber ring structure is a two-fiber-ring laser including an 8 × 8 fiber coupler, a 2 × 2 E/O modulator, and an SOA. The 14-output spectra of the fiber laser are measured. The gain coefficients of each port of the multiple-output-fiber-ring amplifiers are also measured. We apply these two kinds of fiber ring structures in a hybrid CATV and ADSL broadcasting optical fiber communication system. This application can develop a broadcasting system with large coverage area without using many laser diodes and optical amplifiers. The performance of such a system is also analyzed in this article.

Optical transmission beyond the dispersion limit of optical fibers is very important in future optical communications systems. Optical resonators play a major part in several optical equalisation schemes that are required to compensate for the dispersion effects. This paper presents the employment of a double-coupler double-ring optical resonator for equalising optical pulses transmitted through the dispersive medium. A signal flow analysis is briefly given for stating the optical transfer function of the resonator as well as the fundamental aspects of the dispersion of optical pulse through optical fibers. Strategies for equalising dispersive pulses are described with the design of the optical equaliser. Simulated results are given for optical pusle trains with different quiescent points of the resonator.
