A chip architecture that integrates an optical sensor and a pixel level processing element based on binary stochastic arithmetic is proposed. The optical sensor is formed by an array of fully connected pixels, and each pixel contains a sensing element and a Pulse Frequency Modulator (PFM) converting the incident light to bit streams of identical pulses. The processing element is based on binary...
We introduce a high-order time-domain discontinuous spectral element method for the study of the optical coupling by evanescent whispering gallery modes between two microcylinders, the building blocks of coupled resonator optical waveguide devices. By using the discontinuous spectral element method with a Dubiner orthogonal polynomial basis on triangles and a Legendre nodal orthogonal basis on ...
We show that a simple (few-element) arrangement for wavelength-multiplexed digital holography allows the measurement of the electric field E x ,y , t of a femtosecond laser pulse on a single shot. A slightly rotated twodimensional diffractive optical element and a variable-wavelength filter together generate multiple spectrally resolved digital holograms that are simultaneously captured in a si...
In this paper, the performance of an optical modulator based on indium tin oxide is investigated at telecommunication wavelength for different accumulation thickness. The plan of metal-oxide-semiconductor is utilized to change the carrier concentration at indium tin oxide-hafnium oxide interface. An optical mode solver based finite element method has been used to calculate the basic parameters ...
