A novel series of low transition temperature and fast response chiral Smectic C (SmC*) liquid crystals was designed and synthesized. Phase transition behaviors and electro-optical properties of the synthesized compounds were investigated and compared. Ferroelectric [...]
Zinc sulfide (ZnS) is one of the most widely used infrared transmitting window and lens materials for systems operating in the long wave range (8~12 ㎛). ZnS nanoparticles have been intensively studied because of their [...]
In solar photovoltaic systems, enhancing absorption of the incident light on the device surface through reducing reflection is crucial for improving the system performance. In the traditional layered method for anti-reflective coatings (ARCs), however, there [...]
We propose an approach to achieve a great enhancement and broad spectral tunability of the chiro-optic response of plasmonic metasurfaces by exploiting their interaction with light of complex polarization, endowed with both spin (SAM) and [...]
We present a full-wave computational model to study the optical behavior of a versatile sinusoidal grating-based surface plasmon-coupled emission (SPCE) biosensor. Surface plasmons (SPs) are coherent oscillations of conduction electrons on a metal surface excited [...]

We present the design of 160-channel, 50-GHz Si3N4 based AWG applying our proprietary AWG-Parameters tool. For the simulations of the AWG layout, we used PHASAR photonics tool from Optiwave. The simulated transmission characteristics were then [...]
Ultraviolet (UV) photodetectors (PDs) have useful applications including flame detection, environmental monitoring, early missile threat warning systems, etc. UV PDs based on wide-band-gap materials, such as GaN and ZnO have a visible-blind advantage over silicon-based [...]
Soft-lithography and nanoimprinting lithography have been critical in manufacturing 3D features with sub-20 nm resolution onto polymeric materials which have often been employed for producing micro and nanoscale optical materials and surfaces. However, methods for [...]
Light-harvesting systems and plasmonic materials continue to garner significant attention due to their importance in both energy conversion and sensitive detection technologies. However, several challenges exist in improving their performance: these electronic multifunctional systems are [...]
