TLDR
In this paper, the phase noise of six different types of singlemode diode laser in an unbalanced Michelson interferometer was measured as a function of optical path difference.Abstract:
Measurements have been made of the phase noise of six different types of single‐mode diode laser in an unbalanced Michelson interferometer, as a function of optical path difference. The frequency dependence of the phase noise has also been determined. Possible origins of the frequency fluctuations which result in the phase noise are discussed. The detrimental effect of the phase noise on the sensitivity and dynamic range of optical fiber interferometer sensors is briefly discussed.read more

Fiber-optic lattice signal processing
TL;DR: In this paper, the authors discuss the implementation of fiber-optic lattice structures incorporating singlemode fibers and directional couplers, and show that the pole of the system transfer function with the largest magnitude is simple and positive-valued (in the Z-plane), and that the magnitude of the frequency response can nowhere exceed its value at the origin.

1/F Frequency Noise Effects on Self-Heterodyne Linewidth Measurements for Coherent Communications
TL;DR: In this article, the autorcorrelation function and power spectrum of the self-heterodyne photocurrent were developed in terms of an arbitrary frequency noise. And the effect of 1/f frequency noise on the detection performance was analyzed and the results were applied to the problem of laser diode-linewidth measurement.

TL;DR: In this paper, the authors investigated the effect of light reflected from an optical system on injection laser output intensity and spectrum, and showed that reflected light from a near-field region causes power deviation and an oscillating wavelength shift.

Magnetic-field sensing with a single-mode fiber.
TL;DR: A fiber-optic magnetic-field sensor is constructed by bonding a single-mode fiber to a nickel cylinder by means of the magnetostrictive effect, permitting detection of fields as small as 4.4 x 10(-6) Oe/m of fiber.
