Integrating Phase Change Material into Optoelectronic Memory Device with Multi-states and High Performance
Hsin-Hua Chen;Yang Chen;Kuo-Ping Chen

In this research, an optoelectronic memory device based on a phase change material (PCM) was demonstrated. Electrical tuning optical states of VO2 thin films can be realized by integrating VO2 on high conductivity substrates. During operations, large transmittance change (28.6%), multiple states (8 levels) and fast memory performance was achieved.

Silicon-doped micro-heaters based on multimode interference waveguide on silicon-on-insulator
Shu-Min Huang;Song-Jyun Ke;Tzu-Hsiang Yen;Yung-Jr Hung

We demonstrate an efficient silicon heater based on multimode interference waveguide. A power consumption of only 2.62 mW/pi is obtained by creating air trenches beneath silicon heater to avoid heat leakage to the substrate, at the expense of slow dynamic response with a rise/fall time of up to 500 us.

Grating-assisted wavelength division multiplexer/de-multiplexer with reduced channel crosstalk
Chia-Chen Chou;Tai-Chun Wang;Tzu-Hsiang Yen;Yung-Jr Hung

We achieved -30 dB channel crosstalk in wavelength multiplexer/demultiplexer by connecting grating-based transmission filters to the channel outputs of cascaded Mach-Zehnder interferometers with a low insertion loss of 1~2 dB. This approach is promising for applications that require a tight channel spacing and a low channel crosstalk.

Nearly perfect circularly-polarized photonic-crystal mode at exceptional point
Pi-Ju Cheng;Chi-Ti Hsieh;Shu-Wei Chang

We present the criteria for constructing circularly-polarized-like photonic-crystal modes at exceptional points using the dielectric and loss coupling. The degree of circular polarizations of these modes can nearly reach unity.

Monolithically integrated metalens on silicon photonic waveguides
Ping-Yen Hsieh;You-Chia Chang

We propose a method to design metalenses that can be monolithically integrated on
silicon waveguides. We construct the building library of meta-atoms that are evanescently cou-
pled to a waveguide. We verify the design numerically using full-wave simulation. The designed
cylindrical metalenses show di raction-limited performance of Strehl ratios greater than 0.82.

Modulation of Photonic Crystal Patterns Enabling Variable Output Beam Direction of PCSELs
Wei-Chih Weng;Kuo-Bin Hong;Lih-Ren Chen;Tien-Chang Lu

We perturbed position of holes in supercells for design of photonic crystal surface emitting lasers (PCSELs) enabling beam direction manipulation. The mechanism of deflection of output beam direction was depicted through band diagram, Fourier transform and far-field simulations. Such kind of PCSEL is promising for 3D sensing application.

Unidirectional Propagation and Detection in Surface Plasmon Polaritons Waveguides
Chia-Hung Wu;Ji-Ren Ku;Min-Wen Yu;Kuo-Ping Chen

In this research, a direction tunable plasmonic waveguide was demonstrated. Via designed nanostructures, surface plasmon resonance was observed through scattering. Unidirectional propagating surface plasmon polaritons (SPPs) was generated through different polarizations of light. The left channel scattering intensity is measured with a 6 fold enhancement than the right channel.

Synthesis and integration of hybrid organic-inorganic perovskite-based resonators
Wei Zhang;Tsung Sheng Kao

Abstract: We intend to develop an improved growth process to synthesize different building blocks of the perovskite-based resonators in an integrated photonic system. Their optical performance and interaction network will be further investigated.
