Nd-Doped Polymer Waveguide Amplifiers

IEEE Journal of Quantum Electronics, 2010
Nd3+-complex-doped polymer channel waveguide amplifiers with various lengths and Nd3+ concentrations are fabricated by a simple procedure. Internal net gain at 840–950 nm and 1064 nm is experimentally and theoretically investigated under continuous-wave excitation at 800 nm.

Single-mode rib polymer waveguides and electro-optic polymer waveguide switches

Optics and Lasers in Engineering, 2002
Abstract Mode-matching and effective index methods are used to analyze single-mode operation of optical rib polymer waveguides. Their single-mode waveguiding conditions are determined. Single-mode rib waveguides fabricated from guest–host polyetherketone are presented. The estimated propagation loss of straight rib-waveguides is 0.7 dB/cm at 1.55 μm.

Waveguide Raman spectroscopy of polymers and polymer laminates

Journal of Raman Spectroscopy, 1993
AbstractThe Raman waveguide spectra of a series of polymer laminates obtained using a simple optical waveguide coupling device are reported. The optical properties of these polymer films were obtained by measuring the waveguide coupling angles and the resulting electric field calculations were shown to predict (semiquantitatively) the observed spectra ...

Polymer-clad electrospun polymer nanofiber waveguides

Materials Letters, 2013
Abstract We fabricated electrospun polymer nanofiber waveguides composed of a poly(methyl methacrylate) nanofiber core doped with an organic dye and a Cytop cladding. Photoluminescence (PL) spectra are measured at the end face of individual cores with increasing distance ( d ) between the end face and the point of irradiation by the excitation laser ...

Polymer Waveguide-Based Reservoir Computing

2017
Polymer waveguide optical interconnect technology, in which VCSEL and photodiode chip arrays are flip-mounted on an organic carrier to fabricate optical multi-chip modules, has been intensively developed over the last 15 years for data transfer applications in high performance computers. In that application, multiple-channel data signals transmitted to

Polymer Waveguides in Integrated Optics

1990
Future optical communication and optical signal processing systems will require a variety of passive and active optical components. Recently, some polymers with attractive processing properties have been developed and there has been a significant increase in interest in using such organics as optical waveguide materials to form different waveguide ...
