The terahertz modulator includes a plasmon and a cavity. The present disclosure discloses the resonance absorption mechanism caused by collective oscillation of electrons (plasma wave, namely, the plasmon). In order to enhance the coupling strength between the terahertz wave and the plasmon, a GaN/AlGaN high electron mobility transistor structure having a grating gate is integrated in a terahertz Fabry-Pérot cavity, and a plasmon polariton is formed arising from strong coupling of the plasmon and a cavity mode.

Abstract: A tunable PLC optical filter having sequentially connected thermally tunable Mach-Zehnder (MZ) interferometers is described. The cascade of MZ interferometers, each having a free spectral ranges matching ITU frequency grid spacing, are tuned so as to have a common passband centered on the frequency of the signal being selected, while having at least one of the stopbands centered on any other ITU frequency. Any other optical channel that may be present at any other ITU frequency is suppressed as a result. Another MZ interferometer in series with the cascade of interferometers including an asymmetric or variable coupler, is tuned to have low transmission at the center frequency of the selected optical channel.

Abstract: An image decoding system provides a phase pattern encoding a target image. A spatial light modulator is configured to emit a wavefront-shaped light signal based on the phase pattern. A first diffusive medium receives the wavefront-shaped light signal and to emit a decoded scattered light signal of the target image. The target image is previously encoded in the phase pattern by transmitting another wavefront-shaped light signal shaped by a training phase pattern through a second diffusive medium to yield a scattered light signal encoding a test image. The second diffusive medium has the optical scattering characteristics of a first diffusive medium. The scattered light signal encoding the test image is emitted from the second diffusive medium and recorded. The training phase pattern is adjusted for successive iterations of the test image until the test image satisfies a compensation condition. The resulting training phase pattern yields the phase pattern.

Abstract: A thin film photonic structure that enables segregation of the effective absorption of the thin film and its intrinsic absorption while substantially eliminating bandwidth restrictions. In the form of an optical resonator, the structure includes two, multi-layer, aperiodic dielectric mirrors and a lossy, dielectric thin film and characterized by an intrinsic optical absorption over at least a one octave bandwidth. The two, multi-layer, aperiodic dielectric mirrors are characterized by a reflectivity amplitude that increases in-step with increasing wavelength over the at least one octave bandwidth. Upon a single incoherent beam of optical radiation having a spectrum over the at least one octave bandwidth incident on one side of the resonator structure, the lossy, dielectric thin film is characterized by an effective optical absorption over the at least one octave bandwidth that is greater than the intrinsic optical absorption over the at least one octave bandwidth.
