Optical fibers are particularly suitable for remote, microscopic, and in-situ applications due to
their small size, diverse integration capabilities, and low insertion loss. However …

Low-loss optical-coupling structures are highly relevant for applications in fields as diverse
as information and communication technologies, integrated circuits, or flexible and highly …

We present a unique method that utilizes high intensity core of the zero-order nondiffracting
beam (NDB) to fabricate a homogeneous polymer fiber as narrow as 2 μm and as long as …

We present experimental and theoretical study of the interaction of Light Induced Self-
Written (LISW) waveguides in photopolymers. We show that the diffusion of the monomer …

For different depth and width of the intermediate layer, a power flow equation is used to
calculate spatial transients and steady state of power distribution in W-type optical fibers …

Using the power flow equation, we have calculated spatial transients of power distribution
and a steady-state distribution that are due to coupling of guided to leaky modes in W-type …

We report the observation of a self-written waveguide inside a bulk methylene blue
sensitized poly/vinyl alcohol)/acrylamide photopolymer material. Light from a low power He …

A method is proposed for investigation of transmission along a multimode W-type (doubly
clad) plastic optical fiber (POF) with graded index (GI) distribution of the core. The multimode …

The light-induced self-written (LISW) optical waveguide technique has emerged as a
promising solution for achieving passive alignment between telecommunication and silicon …

The bandwidth of multimode W-type plastic optical fibers (POFs) with graded-index (GI) core
distribution is investigated by solving the time-dependent power flow equation. The …
