“…Both properties of such passively modelocked lasers (PMLL) found application in various scientific and industrial areas. Short optical pulses are widely used in high resolution imaging [1], optical signal processing [2] and time-resolved measurements [3]. Due to the high spectral density and coherence of the laser modes the PMLL can be considered as a promising source for wavelength-division multiplexing systems [4] or high speed spectroscopy [5].…”

Abstract:In this paper, we present the detailed characterization of a semiconductor ring passively mode-locked laser with a 20 GHz repetition rate that was realized as an indium phosphide based photonic integrated circuit (PIC). Various dynamical regimes as a function of operating conditions were explored in the spectral and time domain. A record bandwidth of the optical coherent comb from a quantum well based device of 11.5 nm at 3 dB and sub-picosecond pulse generation is demonstrated.

“…The practical on-chip integration applications require several key indexes for these nanoscale all-optical logic devices: ultrasmall feature size, ultralow threshold power, ultrahigh contrast ratio, as well as on-chip trigger [2,3]. More often than not, highly nonlinear fibers [4][5][6], optical asymmetric demultiplexers [7,8], and bulk periodically poled lithium niobate crystals [9][10][11] are used to demonstrate all-optical logic functions. The large size of the bulk materials and lumped components, having a feature size of several centimeters, limits the practical on-chip integration applications [12,13].…”

Ultracompact chip-integrated all-optical halfand full-adders are realized based on signal-light induced plasmonic-nanocavity-modes shift in a planar plasmonic microstructure covered with a nonlinear nanocomposite layer, which can be directly integrated into plasmonic circuits. Tremendous nonlinear enhancement is obtained for the nanocomposite cover layer, attributed to resonant excitation, slow light effect, as well as field enhancement effect provided by the plasmonic nanocavity. The feature size of the device is <15 μm, which is reduced by three orders of magnitude compared with previous reports. The operating threshold power is determined to be 300 μW (corresponding to a threshold intensity of 7.8 MW/cm 2 ), which is reduced by two orders of magnitude compared with previous reports. The intensity contrast ratio between two output logic states, "1" and "0," is larger than 27 dB, which is among the highest values reported to date. Our work is the first to experimentally realize on-chip halfand full-adders based on nonlinear plasmonic nanocavities having an ultrasmall feature size, ultralow threshold power, and high intensity contrast ratio simultaneously.This work not only provides a platform for the study of nonlinear optics, but also paves a way to realize ultrahighspeed signal computing chips.

“…Owing to the benefits that photonics devices offer over its electronics counterparts, ultra response is promising along with huge increase in capacity (Mehra et al, 2012;Li et al, 2007;Stubkjaer, 2000;Schreicek et al, 2002;Vlachos et al, 2003). In the last decade and due to recent development in nonlinear optical materials, works and interests on optical computing have increased (Gosh et al, 2012;Gayen et al, 2011).…”

10.7603/s40632-014-0005-0All-optical polarization-encoded negabinary signed-digit adder designs using terahertz-optical-asymmetric-demultiplexer switches 64All-optical polarization-encoded negabinary signed-digit adder designs using terahertz-optical-asymmetric-demultiplexer switches ABSTRACTIn contrast to intensity-encoded negabinary modified signed-digit number representation, a polarization-encoding scheme is proposed to design all-optical adders. The utilization of the proposed polarization-encoding produces more efficient circuits in terms of gates numbers and circuit delays. Three all-optical adder circuits are designed using Terahertz-OpticalAsymmetric-Demultiplexer (TOAD) switches, polarization beam splitters, polarization converters, and beam combiners. It will be shown that the proposed circuits utilize 51.7%, 45.5%, and 21% less gates and they are faster by 44.4%, 42.9%, and 40%, respectively, than the corresponding intensity-encoded circuits.
