It should be noted that the implementation of two sectional PML lasers is technically easier than creating a high-speed modulator, because there is no need to eliminate parasitic capacitance and inductance.
This chapter reviews the theory of high-speed modulators and practical design approaches, which include a comparison of lumped and traveling-wave designs, and experimental results.
This quantum-confined Franz-Keldysh effect [ 8– 12] is employed in the design of the devices of integrated optics, such as high-speed modulators [ 13], optically bistable switches [ 14] and wavelength selective detectors [ 15].
In addition to the advantages associated with the slow group velocity, photonic crystal waveguide modulators are found to exhibit other structural and optoelectronic merits for high speed modulation.
Shrinking component sizes will also speed the modulator.
In this paper, we propose a novel compact and ultra-high speed optical modulator, the performance of which is validated by 2D and 3D simulations.
In this paper, a new type of high-speed EO modulator is presented.
The dwell time in SPOM-NOM can be improved to the order of microseconds by shot-noise-limited detection using a high-speed pointing modulator such as an electro-optic deflector.
We simulate thin-film based electro-optic modulator structures to target low drive voltage, high-speed modulation, and small device size by using BaTiO3 ferroelectric film as an exemplary device material with optimizing film thickness.
In addition, the small electron effective mass, the small band gap, and the high electron mobility of InGaAs alloys are important for the development of high electron mobility transistors, high-speed detectors, modulators, and THz emitters [19 22].
Due to its unique optical properties, graphene has been recently utilized in the fabrication of optical modulators, which promise high performance such as broadband response, high modulation speed, and high modulation depth.
