In this paper, the electrochromic device with functions of rapid duty cycle and infrared (IR) suppression. The electrochromic device is simultaneously not only having high optical modulation but also IR-suppression by using the multilayered AZO/Ag/AZO structure. The AZO/Ag/AZO structure is using to be transparent electrode and the nano-crystalline WO3 is using to be electrochromic layer. The electrochromic...
A Mach-Zehnder modulator based on a hybrid BaTiO3/silicon optical waveguide has been designed to achieve a high modulation bandwidth with a simulated VπL below 1V·cm and RF impedance matching. The device has been fabricated and characterized in the DC regime.
We present a 20 Gb/s monolithically integrated transmitter with stacked CMOS driver and periodic-loaded PN-junction Mach-Zehnder modulator fabricated in IBM's sub-100nm technology node. Transmitter extinction ratios of 10 dB at 20 Gb/s are demonstrated.
In this paper, we present a new type of photonic interface that is capable of conveying a receive signal from an antenna while simultaneously conveying a transmit signal to the same antenna. We call this interface a TIPRx, which is short for transmit-isolating photonic receiver. We first present the TIPRx theory of operation, and then focus on the key figures of merit: the degree of suppression of...
Travelling wave electrode Mach-Zehnder modulators in InP/InGaAsP are investigated for application to advanced digital optical fibre formats. Single-end 50-Ohm and novel differential 100-Ohm designs are described.
Amplitude and phase characterization of the output from a dual-electrode LiNbO3 Mach-Zehnder modulator based ultra-flat optical frequency comb generator is investigated for well-known ldquoin-phaserdquo operation and a new ldquoout-of-phaserdquo regime. The out-of-phase regime may be realized with a single-electrode Mach-Zehnder modulator.
This article describes development and construction of an evolutional lumped constant type LiNbO3 optical modulator that operates via a faint signal in the microwave frequencies for TV program transmission of terrestrial digital TV broadcasting with a bandwidth of 6–9MHz. This modulator modulates a light beam at 1.5µm with OFDM (Orthogonal Frequency Division Multiplex) signals at a 6–7GHz band and...
