Light Emission from Rare-Earth Doped Silicon Nanostructures
Light Emission Rare-Earth Doped Silicon Nanostructures
2009/5/19
Rare earth (Tb or Ce)-doped silicon oxides were deposited by electron cyclotron resonance plasma-enhanced chemical vapour deposition (ECR-PECVD). Silicon nanocrystals (Si-ncs) were formed in the silic...
Slow Light with Photonic Crystals for On-Chip Optical Interconnects
Slow Light Photonic Crystals On-Chip Optical Interconnects
2009/5/19
Transistor scaling alone can no longer be relied upon to yield the exponential speed increases we have come to expect from the microprocessor industry. The principle reason for this is the interconnec...
High-Efficiency Intracavity Continuous-Wave Green-Light Generation by Quasiphase Matching in a Bulk Periodically Poled MgO:LiNbO3 Crystal
Quasiphase Matching LiNbO3 Crystal
2008/10/31
908 mW of green light at 532 nm were generated by intracavity quasiphase matching in a bulk periodically poled MgO:LiNbO3 (PPMgLN) crystal. A maximum optical-to-optical conversion efficien...
Tungsten black absorber for solar light with wide angular operation range
Tungsten black absorber solar light wide angular operation range
2008/8/10
Using three-dimensional finite-difference time-domain simulations, we designed a structured tungsten slab with subwavelength periodicity that displays near-complete absorptivity throughout the e...
Slow Light Enhanced Third-Harmonic Generation in Silicon Photonic Crystal Waveguides
Third-Harmonic Silicon Photonic Crystal Waveguides
2008/8/6
We report visible (green) third-harmonic generation in silicon by launching near-infrared picosecond pulses into highly confined photonic crystal waveguides. We demonstrate slow light enhancement of t...
Tunable Slow Light in Semiconductor Optical Amplifier without External Pump Laser
Tunable Slow Light Semiconductor Optical Amplifier External Pump Laser
2008/8/6
This investigation experimentally demonstrates tunable slow light in a semiconductor optical amplifier (SOA) without an external pump laser. Tunable time delays are achieved by adjusting the feedback ...
Pulse broadening of zero-gain Brillouin slow light in an optical fiber
Pulse broadening zero-gain Brillouin slow light optical fiber
2008/8/4
We investigate pulse-broadening effects of zero-gain Brillouin slow-light (ZGBSL) in an optical fiber. The results show that the stored-capacity of ZGBSL is less than that of SBS amplifier-based slow-...
Cancellation of Pulse Walk-off in Raman Amplifiers via Slow Light
Pulse Walk-off Slow Light
2008/8/4
We theoretically demonstrate in an optical fibre system that Raman pulse walk-off can be cancelled by Raman-induced slow light, leading to group-velocity matching and to an enhanced Raman gain efficie...
Wavelength Resource Scalable Heterodyne Detection Based WDM Access Employing Time-Domain Modulation of Wavelength-Swept Light
Wavelength Resource Employing Time-Domain Modulation Wavelength-Swept Light
2008/7/31
Wavelength resource scalable heterodyne detection based WDM access employing time-domain modulation of wavelength-swept light is proposed. We experimentally demonstrate 1ch ～ 5ch 12.5 GHz-spaced 1.0 G...
Stopping and time reversing a light pulse using dynamic loss tuning of coupled-resonator delay lines
time reversing light pulse dynamic loss tuning coupled-resonator delay lines
2007/8/10
We introduce a light-stopping process that uses dynamic loss tuning in coupled-resonator delay lines. We demonstrate via numerical simulations that increasing the loss of selected resonators traps lig...

We present a general analysis for the criteria to stop and store light coherently. We show that a light pulse can be stopped in any physical system, provided that (i) the system bandwidth can be compr...
Coupled optical and electronic simulations of electrically pumped photonic-crystal-based light-emitting diodes
Coupled optical electronic simulations electrically pumped light-emitting diodes
2005/8/11
We use coupled optical and electronic simulations to investigate design trade-offs in electrically pumped photonic-crystal-based light-emitting diodes. A finite-difference frequency-domain elect...
Time Reversal of Light with Linear Optics and Modulators
Time Reversal Light Linear Optics Modulators
2004/8/11
We introduce a new physical process that can perform a complete time-reversal operation on any electromagnetic pulse. The process uses only small refractive index modulations of linear optical element...
