Highly sensitive 2D Si photonic crystal (PhC) sensor is proposed and analyzed for the detection of gamma-ray doses in the visible light region. The suggested PhC has a cavity infiltrated by poly-vinyl alcohol (PVA) polymer doped with crystal violet and carbol fuchsine dyes. The geometrical parameters of the design are studied to maximize the sensor […]

An asymmetric dual core photonic crystal fiber (ADC-PCF) tunable polarization splitter is reported and analyzed. The left core of the DC-PCF is infiltrated with nematic liquid crystal (NLC) material to control the wavelength at which coupling occurs between the dual cores of the proposed structure. Moreover, the suggested design can be tuned to split out […]
