The purpose of this experiment was to observe the wave-particle duality of photons by demonstrating that single photons can and do interfere with themselves. This was accomplished through the use of a Mach-Zehnder interferometer and a Young double slit apparatus. The EMCCD camera used for both experiments can detect single photons to some degree, thus demonstrating the particle nature of photon...
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...
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...
An InGaAsP-InP optical switch geometry based on electrical control of waveguide-resonator coupling is demonstrated. Thermooptic tuning of a Mach-Zehnder interferometer integrated with a racetrack resonator is shown to result in switching with ON-OFF contrast up to 18.5 dB. The optical characteristics of this unique design enable a substantial reduction of the switching power, to a value of 26 m...
A re-visitation of the well known free space Mach Zehnder interferometer is here reported. Coexistence between one-photon and two-photons interference from collinear color entangled photon pairs is investigated. This is seen to arise from an arbitrarily small unbalance in the arm transmittance. The tuning of such asymmetry is reflected in dramatic changes in the coincidence detection, revealing...
