Compact high-performance electro-optic (EO) modulators are key elements for optical communications. An electro-absorption modulator is theoretically designed. Due to the introduction of graphene film… Expand
Thermal UV treatment on SU-8 polymer for integrated optics
We report a simple and low-cost method to fabricate SU-8-based polymer waveguide devices. The influence of hard-baking temperature on SU-8 polymer treated with or without UV radiation was… Expand
650-nm 1 × 2 polymeric thermo-optic switch with low power consumption.
In this paper, a low-power 1 × 2 polymeric thermo-optic switch operating at the polymer optical fiber low-loss window of 650 nm was studied. The characteristic parameters of the switch were carefully… Expand

Waveguide amplifiers have always been significant key components for optical communication. Unfortunately, the low concentration of rare earth ions doped in the host material and the inadequate… Expand
Improved performance of thermal-optic switch using polymer/silica hybrid and air trench waveguide structures.
By exploiting the polymer/silica hybrid and the air trench waveguide structures, we demonstrate a new type of low-power consuming and high-speed thermal-optic (TO) switch. Such a design provides an… Expand
Surface plasmon resonance refractive index sensor based on ultraviolet bleached polymer waveguide
Abstract In this paper, a compact refractive index (RI) sensor based on the resonant interaction between surface plasmon polaritons (SPP) mode and polymer waveguide mode is demonstrated. The hybrid… Expand
Buried graphene electrode heater for a polymer waveguide thermo-optic device.
We propose the use of graphene as the electrode heater material for a polymer waveguide thermo-optic (TO) device. Because a graphene electrode can be buried in a polymer waveguide without introducing… Expand
New anisopleural spindle-like nonlinear optic (NLO) chromophores with a D–D′–π–A′–A or D–A′–π–D′–A structure: interesting optical behavior and DFT calculation results
A new series of anisopleural spindle-like chromophores which have both auxiliary donors and acceptors on their conjugated bridge has been designed and synthesized for the first time. The auxiliary… Expand
Optical waveguide amplifiers based on NaYF_4: Er^3+, Yb^3+ NPs-PMMA covalent-linking nanocomposites
NaYF4: Er3+, Yb3+ nanoparticles (NPs) were synthesized by using a high temperature thermal decomposition approach. Under a 980 nm laser excitation, intense emission at 1.53 μm from NaYF4: Er3+,Yb3+… Expand
