Numerical investigation of all-optical add-drop multiplexing for spectrally overlapping OFDM signals
Background and Aim: Bioaerosols are one of the most important agents that cause post operating infections in hospitals. Surgical masks are recommended for prevention of bioaerosols transmition in operating rooms. This study aimed at evaluation of submicron particle filtration efficiency of domestic and imported surgical masks. Materials and Methods: In this cross sectional study, 5 types of...
We demonstrate a silica-based tunable fiber Bragg grating (TFBG) filter with a wavelength tuning range over 60 nm. A magnetically TFBG package is employed to obtain a wide wavelength tuning range from 1540 to 1602 nm which covers the entire C band and most of the L-band. TFBG is achieved by varying an input current to a solenoid, resulting in an electromagnetic force, used as a strain (tension ...
BACKGROUND A novel nanomicro syringe system was proposed for drug storage and delivery using a PANDA ring resonator and atomic buffer. A PANDA ring is a modified optical add/drop filter, named after the well known Chinese bear. In principle, the molecule/drug is trapped by the force generated by different combinations of gradient fields and scattering photons within the PANDA ring. A nanomicro ...
Abstract The multi-dimensional multiplexing technology is very promising for further increasing the link capacity of optical interconnects. A 96-channel silicon-based on-chip reconfigurable add-drop multiplexer (ROADM) proposed and demonstrated first time to satisfy demands in hybrid mode/polarization/wavelengthdivision-multiplexing systems. present ROADM consists a six-channel mode/polarizatio...
The rich potential of the microwave experiments for characterization and optimization of optical devices is discussed. While the control of the light fields together with their spatial mapping at the nanoscale is still laborious and not always clear, the microwave setup allows to measure both amplitude and phase of initially determined magnetic and electric field components without significant ...
