Metamaterials are artificially structured materials that can produce innovative optical functionalities such as negative refractive index, invisibility cloaking, and super-resolution imaging. Combining metamaterials with semiconductors enables us to develop novel optoelectronic devices based on the new concept of operation. Here we report the first experimental demonstration of a permeability-c...
In the present paper, the inference of Cross-Phase Modulation and Cross Gain experiments on InGaAsP-based semiconductor optical amplifiers and Mach-Zehnder Interferometer (MZI) switches along with a novel characterization method for semiconductor optical amplifiers MZI switches which combines a pump-probe measurement with an interferometer bias scan are shown. For the 150-fs input pulses, a str...
The wave-particle duality of light was verified by multi and single photon interference both through Young’s double slit and Mach-Zehnder interferometer. In these two sets of experiments, the interference in the single photon level is the same as that at multi photons level with long enough exposure time. In the Mach-Zehnder interferometer, the “whichpath” information can be identified by measu...
The emerging field of silicon photonics [1-3] targets monolithic integration of optical components in the CMOS process, potentially enabling high bandwidth, high density interconnects with dramatically reduced cost and power dissipation. A broadband photonic switch is a key component of reconfigurable networks which retain data in the optical domain, thus bypassing the latency, bandwidth and po...
Silicon photonic-wire waveguide is one of the most promising platforms in constructing compact optical devices, since the waveguide can be bent with a radius of less then several microns. Recently, we have demonstrated various optical devices based on silicon photonic-wire waveguides, which include a directional coupler, a tunable optical add-drop multiplexer, and some ultra-compact 1 x N optic...
In this work we have designed a Mach Zehnder interferometer (MZI) for electro optic modulator at telecommunication wavelength using GaN on Sapphire. The knowledge of GaN sample optical properties were also investigated, resulting refractive index for the GaN layers were found to be nTE=2.279±0.001 and nTM = 2.316±0.001 and good temperatur stability. Optimization of the structure parameters and ...
We demonstrated a compact and highly-sensitive curvature sensor based on a Mach-Zehnder interferometer created in a photonic crystal fiber. Such a Mach-Zehnder interferometer consisted of a peanut-like section and an abrupt taper achieved by use of an optimized electrical arc discharge technique, where only one dominating cladding mode was excited and interfered with the fundamental mode. The u...
