The oscillation spectral linewidth and the oscillation frequency of a laser diode with an external cavity have been stabilized simultaneously with an optical fiber ring resonator used as a spectrum discriminator. Stabilization of the oscillation spectrum linewidth has been carried out with control of the phase of the fed‐back light and the oscillation frequency by control of the injected current. The oscillation spectral linewidth is 2 MHz and its fluctuation is less than 10 kHz p‐p and the equivalent oscillation frequency fluctuation is 2 MHz p‐p From these results, it is confirmed that an external cavity laser diode can be used as a light source of a ring resonator‐type fiber gyroscope.

Abstract-A single-mode fiber-optic ring resonator is used as a multipath reference for multiplexing white light interferometric sensors. The theory of applying the resonator for multiplexing Michelson-type interferometer sensor is presented. The capacity of the technique in terms of maximum sensor number is evaluated for both a linear array and a sensor matrix. Experimental results for a three-sensor linear array and 2 1 sensor matrix are also presented.Index Terms-Multiplexing, optical fiber sensors, ring resonator, white light interferometry.

“…Recently some of the semiconductor ring lasers have been realized based on preliminary fiber ring laser research [14,15]. The ring-type lasers have many advantages, such as high-power mode-locking output [16][17][18][19][20], narrow linewidth [21][22][23], no facet coating problem, and so forth. However, there has been no particular development and application of multiple fiber ring structures with optical amplifiers for spatial signal distributions in local area access networks.…”

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.
