Segmented waveguides in thin silicon-on-insulator [PDF]

open access: yes, 2005
We have developed new silicon-on-insulator waveguide designs for simultaneously achieving both low-loss optical confinement and electrical contacts, and we present a design methodology based on calculating the Bloch modes of such segmented waveguides ...

All-optical high speed NOR gate based on two photon absorption in silicon wire waveguides [PDF]

open access: yes, 2006
We demonstrate for the first time an all-optical logic NOR gate in submicron size silicon wire waveguides. High speed operation at equivalent 80Gbps data rate was achieved using pump induced non-degenerate two-photon absorption inside the waveguides. The

Source misalignment in multimode polymer tapered waveguides for optical backplanes [PDF]

open access: yes, 2007
Polymer tapered multimode waveguides were modeled using the finite difference wide-angle beam propagation method to investigate whether tapered input waveguide couplers decreasing in width away from the waveguide entrance give improved tolerance to ...

KONTRUKSI PT-Symmetry MULTI DIMER PADA DOMAIN TAK HINGGA

open access: yesJurnal Lebesgue, 2023
Parity-Time Symmetry, or abbreviated as -Symmetry, can be explained as the propagation of an optical beam in two bound waveguides, where one waveguide experiences strengthening and the other waveguide experiences weakening, with each intensity having the

Diamond photonics platform enabled by femtosecond laser writing [PDF]

open access: yes, 2016
We demonstrate the first buried optical waveguides in diamond using focused femtosecond laser pulses. The properties of nitrogen vacancy centers are preserved in the waveguides, making them promising for diamond-based magnetometers or quantum information

Calculation of fully anisotropic liquid crystal waveguide modes [PDF]

open access: yes, 2009
The accurate analysis of optical waveguides is an important issue when designing devices for optical communication. Waveguides combined with liquid crystals have great potential because they allow waveguide tuning over a wide range using low voltages. In

Properties of Multimode Optical Epoxy Polymer Waveguides Deposited on Silicon and TOPAS Substrate [PDF]

open access: yesRadioengineering, 2017
The paper reports on the fabrication and characterization of multimode polymer optical waveguides. Epoxy polymer EpoCore was used as the waveguide core material and EpoClad was used as a cladding and cover protection layer.

Properties of Large Core Polymer Optical Bend Waveguides [PDF]

open access: yesRadioengineering, 2019
We report about properties of large core plastic planar optical bend waveguides. The dimensions of the waveguides were to be compatible with the commonly used plastic optical fiber with diameter 750 µm and the bend radii of the waveguides varied from 30 ...

Polymeric Optical Waveguide

open access: yesThe Review of Laser Engineering, 1992
PROBLEM TO BE SOLVED: To satisfy the transparency and heat resistance and further to fulfill the workability and optical isotropy which have been incompatible with heat resistance so far by using a specified polyurethane contg. an asymmetric spiro ring as the optical core and/or optical clad. SOLUTION: A polyurethane shown by the formula and contg.

Cascaded Integration of Optical Waveguides With Third-Order Nonlinearity With Lithium Niobate Waveguides on Silicon Substrates

open access: yesIEEE Photonics Journal, 2018
The cascaded integration of optical waveguides with third-order optical nonlinearity ( $\chi ^{(3)}$ susceptibilitiy) with lithium niobate (LiNbO $_{3}$) waveguides is demonstrated on the same chip.
