Journal ArticleDOI
Micrometre-scale silicon electro-optic modulator
TL;DR: Electro-optic modulators are one of the most critical components in optoelectronic integration, and decreasing their size may enable novel chip architectures, and here a high-speed electro-optical modulator in compact silicon structures is experimentally demonstrated.
Journal ArticleDOI
Guiding and confining light in void nanostructure.
TL;DR: It is shown that by use of a novel waveguide geometry the field can be confined in a 50-nm-wide low-index region with a normalized intensity of 20 microm(-2), approximately 20 times higher than what can be achieved in SiO2 with conventional rectangular waveguides.
Journal ArticleDOI
12.5 Gbit/s carrier-injection-based silicon micro-ring silicon modulators
TL;DR: A scheme for achieving high-speed operation for carrier-injection based silicon electro-optical modulator, which is optimized for small size and high modulation depth is shown.
Journal ArticleDOI
Experimental demonstration of guiding and confining light in nanometer-size low-refractive-index material.
TL;DR: A novel silicon waveguide structure for guiding and confining light in nanometer-wide low-refractive-index material is experimentally demonstrated and it is shown that the structure can be implemented in highly integrated photonics.
Journal ArticleDOI
Experimental realization of an on-chip all-optical analogue to electromagnetically induced transparency
TL;DR: In this article, the authors provided the first experimental observation of structure tuning of the electromagnetically induced transparency-like spectrum in integrated on-chip optical resonator systems and measured a transparency-resonance mode with a quality factor of 11 800.
