We present the applications of a Vernier effect based on cascading two Mach–Zehnder
interferometers (MZIs) as a selectable comb filter and saturable absorber (SA) in an erbium …

In this paper, we report, to our knowledge, the first extended study of the inscription of Bragg
gratings in surface-core fibers and their application in refractive index and directional …

A compact and low cost fiber sensor based on single multimode microfiber with Fresnel
reflection is proposed and demonstrated for simultaneous measurement of refractive index …

In this article, a new and flexible approach to control the electric field enhancement of bow-
tie nano-antennas by integrating them on the lateral of a tapered optical fiber is proposed …

A novel all-fiber mode-locked fiber laser based on microfiber polarizer is proposed and
demonstrated. The microfiber polarizer is composed of two pieces of microfibers that are …

We propose a convenient method for achieving highly birefringent (HiBi) elliptic microfibers
by use of the CO_2-laser machining and the flame-brushing techniques. With optimization of …

We report on an electroabsorption optical modulator using graphene-on-D-microfiber
configuration. Two-lamellae of graphene embedded in the dielectric spacer are incorporated …

This paper presents a fabrication method for 2× 2 twisted fiber-optic directional couplers
based on biconical low-loss tapered optical fibers using a two-step wet-etching technique …

A high sensitivity refractive index (RI) sensor based on balloon-like singlemode-tapered
multimode-singlemode (STMS) fiber structure is proposed. The configuration is formed by …

A highly sensitive sensor based on a D-shaped microfiber with high birefringence is
theoretically and experimentally demonstrated. The fiber is fabricated by side-polishing a …
