TL;DR: In this paper, a concept for self-aligned formation of the p-n junction which is flexible in the capability to produce a number of device configurations is presented, and experimental results from devices which are formed through such processes are presented with operation up to and beyond 40 Gbit/s.
Journal ArticleDOI
High speed silicon optical modulator with self-aligned fabrication process
TL;DR: A novel high speed silicon optical modulator which has self-aligned pn junction formation is introduced and shown to be attractive for reducing performance variations and increasing yield.
Journal ArticleDOI
Frequency comb generation in a silicon ring resonator modulator.

TL;DR: An optical comb of highly uniform in power frequency lines (variation less than 0.7 dB) using a silicon ring resonator modulator is reported on, indicating optimum operation at a small forward-bias voltage.
Journal ArticleDOI
Device-level characterization of the flow of light in integrated photonic circuits using ultrafast photomodulation spectroscopy
Roman Bruck,Ben Mills,Benedetto Troia,David J. Thomson,Frederic Y. Gardes,Youfang Hu,Goran Z. Mashanovich,Vittorio M. N. Passaro,Graham T. Reed,Otto L. Muskens +9 more
TL;DR: In this paper, the authors present a device-level method for characterization of photonic chips based on a highly localized modulation in the device using pulsed laser excitation, and demonstrate the versatility of this all-optical modulation technique in imaging and in quantitative characterization of a variety of properties of silicon photonic devices.
Journal ArticleDOI
