Generation and transmission of 30 GHz MMW beat-tone are reported from a cost-effective injection-locked $mathbf{InAs}/mathbf{InP}$ quantum-dash-laser emitting in extended-L-band. Low phase-noise of ~120dBc/Hz, and successful transmission of 2Gb/s QPSK signal over hybrid 20km fiber and 2m wireless channel is demonstrated.

There is considerable interest in ultra-broadband and high-resolution OCT designs for detecting small features inside biological tissues. Spectral-domain spectrometers linear in wavenumber are of great interest are suggested for such applications. This work describes a new all reflective spectrometer system with improved Strehl ratio, linear wavenumber, and free of chromatic aberration.

Numerical simulations for generating and transmitting four Laguerre-Gaussian (LG) modes over 100m of multimode fiber are conducted. Each LG mode is modulated using 10Gbps NRZ signal. Bit error rate (BER) and Q-factor performance metrics showed acceptable system performance as the worst mode has Q-factor of 9.1 and BER of 2.5E-20.

In this work, a Polarization Sensitive Optical Coherence Tomography (PS-OCT) system is described with the ability of navigation in neurosurgery. Of great importance in neurosurgery is guiding Deep Brain Stimulation (DBS) needle probe which needs precise and detailed navigation within the brain tissue. PS-OCT is a powerful imaging tool that can be used to obtain detailed information within the tissue at different depths based on the low coherent light interferometry and birefringence properties of the tissue by exploiting polarimetric methods. It is noteworthy to mention that PS-OCT exhibits great resolution and sensitivity based on the tissue birefringence related parameters (retardation and optic axis orientation) especially for the precise placement of DBS probe in the subthalamic nucleus (STN), which is entirely surrounded by myelinated fiber bundles that are highly birefringent. In general, images obtained using this system can provide a spatial map of the anisotropic structure of the tissue.

How to obtain key parameters of near-eye displays with a high precision has always been a hot topic both in academic and industry fields. The characteristics of the human eye and the principle of these parameters were imitated and analyzed. Several measurement prototypes have been developed to cover these parameters, such as field-of-view (FOV), angular resolution, eye box, virtual image depth, and motion-to-photon latency.

Thin films of molybdenum trioxide (MoO3) were deposited by thermal evaporation technique on to a glass substrate at different temperatures. The variation of electrical property with temperature as well as with UV irradiation was studied. The substrate temperature seems to affect the electrical property of the deposited films. The electrical resistivity decreases as the substrate temperature decrease. The effect of UV irradiation on samples were systematically investigated with different substrate temperature. All samples were exposed to UV irradiation for one hour. By exposing samples to UV irradiation, electrical resistivity was found to decrease as a function of time. A correlation is established between, UV irradiation, and the substrate temperature of the MoO3 films. This dependence of the substrate temperature is important in the point of view of applications, where the we can control the resistivity of the MoO3 film depending on the application needed.

Cascaded down conversion has been demonstrated as an effective method of directly producing three-photon entanglement. Until now, these sources have relied on intricate active phase stabilization schemes. In this work, we present a completely phase-stable source of three-photon entanglement in the polarization degree of freedom. We produce states with over 96% fidelity with an ideal Greenberger-Horn-Zeilinger state. Moreover, we demonstrate the stability of the source over several days without any ongoing optimization.
