Frequency locking of an erbium-doped fiber ring laser to an external fiber Fabry-Perot resonator [PDF]
, 1993 An all-fiber, single-frequency, erbium-doped ring laser has been frequency locked to a resonance peak of an external fiber Fabry-Perot resonator by the Pound-Drever technique.

Single-mode fiber, velocity interferometry [PDF]
Review of Scientific Instruments, 2011 In this paper, we describe a velocity interferometer system based entirely on single-mode fiber optics. This paper includes a description of principles used in developing the single-mode velocity interferometry system (SMV). The SMV design is based on polarization-insensitive components.

Design of Single Mode Fiber for Optical Communications
Ibn Al-Haitham Journal for Pure and Applied Sciences, 2020 In this work, a step-index fiber with core index and cladding index has been designed. Single-mode operation can be obtained by using a fiber with core diameters 4–13 µm operating at a wavelength of 1.31 µm and by 4–15 µm at 1.55 µm.

Single-Mode Fiber Microlens with Controllable Spot Size [PDF]
, 1991 A novel method for fabricating microlenses on tapered single-mode fibers is shown to be able to control the lens spot size. The fiber cladding is first symmetrically tapered by etching it with an evaporating ammonium bifluoride solution.

Birefringence for Elliptical-Core Fibers with Low Ellipticities
Ibn Al-Haitham Journal for Pure and Applied Sciences, 2022 Model birefringence was measured for elliptical-core fibers with low ellipticities, note the birefringence depends strongly on the frequency, especially when fiber is being operated near the higher mode cutoff where ν for circular fiber of the single ...

High Efficiency Coupling Technology of Silicon Photonic Modulator and Single-Mode Optical Fiber
Guangtongxin yanjiu, 2021 Due to the small mode field of silicon photonic chips, the large coupling loss is a road-blocker for their applications. In this work, the coupling efficiency between a silicon photonic modulator chip and a single-mode optical fiber is investigated.
