Ingår i: Conference Proceedings - Lasers and Electro-Optics Society Annual Meeting-LEOS. - 1092-8081. ; 2020-May
-
Konferensbidrag (refereegranskat)abstract
- The design of a LiNbO3/Si3N4-bilayer vertical coupler is proposed based on adiabatic transition from a thick-Si3N4 strip waveguide to a LiNbO3/thin-Si3N4 striploaded hybrid waveguide having a gross coupling loss of ∼0.08 dB.

Active Mode-Selective Conversion Enabled by an Elliptical-Core Highly Nonlinear Few-Mode Fiber
- 2020
-
Ingår i: Conference Proceedings - Lasers and Electro-Optics Society Annual Meeting-LEOS. - 1092-8081. ; 2020-May
-
Konferensbidrag (refereegranskat)abstract
- We design an elliptical-core highly nonlinear few-mode fiber to achieve mode-selective conversion without parasitic wavelength conversion, using intermodal four-wave mixing. The proposed mode converter can be used in optical cross-connects over the C-band.

Single Dark-Pulse Kerr Comb Supporting 1.84 Pbit/s Transmission over 37-Core Fiber
- 2020
-
Ingår i: Conference Proceedings - Lasers and Electro-Optics Society Annual Meeting-LEOS. - 1092-8081. ; 2020-May
-
Konferensbidrag (refereegranskat)abstract
- We show that a single dark-pulse Kerr comb can generate high enough OSNR to carry 1.84 Pbit/s data, achieved by 223 WDM spectral lines modulated with 32-Gbaud, SNR-adapted probabilistically shaped DP-QAM, over a 37-core fiber.

Sub-Picosecond Time-Dependent Mobility in Low-Band-Gap Polyphenylene:Fullerene Blend Probed by Terahertz Spectroscopy

-
Konferensbidrag (refereegranskat)abstract
- Time-resolved terahertz spectroscopy is used to investigate photoinduced dynamics of charge carriers in a polymer heterojunction. We directly observe instantaneous generation of highly mobile charge carriers followed by a rapid drop in their mobility. (C) 2008 Optical Society of America

Ultrafast Transport in Dye Sensitized ZnO Nanotips Investigated by Terahertz Spectroscopy

-
Konferensbidrag (refereegranskat)abstract
- Transient far-infrared conductivity of as-grown and dye-sensitized ZnO nanotips is measured using time-resolved terahertz spectroscopy. We reveal that the sensitization procedure dramatically affects the transport properties of ZnO nanotips. (C) 2008 Optical Society of America

Coherence in Optics and Transport in Terahertz Quantum Cascade Lasers

-
Konferensbidrag (refereegranskat)abstract
- Coherence in optics and transport is investigated for quantum cascade lasers. While coherence provides oscillations in the gain recovery if the tunnel coupling surpasses the broadening, incoherent hopping transport can fail in the opposite case. (C) 2008 Optical Society of America

25 GHz soliton microcombs in high-Q Si3N4 racetrack-shaped microresonators
- 2020
-
Ingår i: Conference Proceedings - Lasers and Electro-Optics Society Annual Meeting-LEOS. - 1092-8081. - 9781557528209
-
Konferensbidrag (refereegranskat)abstract
- We demonstrate a 25 GHz single-soliton comb on a Si3N4 platform fabricated using a novel subtractive method. A long cavity is carefully designed to fit within the e-beam writing field while minimizing coupling to higher-order modes.
