Reducing Actuation Nonlinearity of MEMS Phase Shifters for Reconfigurable Photonic Circuits
- 2019
-
Ingår i: 2019 CONFERENCE ON LASERS AND ELECTRO-OPTICS (CLEO). - : IEEE. - 9781943580576
-
Konferensbidrag (refereegranskat)abstract
- The low power consumption of MEMS actuators enables large-scale reconfigurable photonic circuits. However, insertion loss and actuation linearity need improvement. By simulations and experiments, we analyze the dominating design parameters affecting linearity and suggest improvements.

Ingår i: 2019 CONFERENCE ON LASERS AND ELECTRO-OPTICS (CLEO). - : IEEE. - 9781943580576
-
Konferensbidrag (refereegranskat)abstract
- We theoretically investigate the formation of frequency combs in a dispersive second-harmonic generation cavity system, and predict the existence of quadratic cavity solitons in the absence of a temporal walk-off. (C) 2019 The Author(s)

-
Konferensbidrag (refereegranskat)abstract
- A continuous-filtering Vernier spectrometer based on an Er:fiber femtosecond laser was developed to acquire broadband H2O and OH spectra in a premixed CH4/air flame with 25 ms time resolution and percent precision on concentrations retrieval.

Ultrafast Transition from Intra- to Interlayer Exciton Phases in a Van Der Waals Heterostructure

-
Ingår i: Optics InfoBase Conference Papers. - 2162-2701. - 9781943580576
-
Konferensbidrag (refereegranskat)abstract
- The binding energy of interlayer excitons is measured by revealing a novel 1s-2p resonance in the mid infrared. Intralayer excitons transform directly into interlayer species via ultrafast electron tunneling strongly influenced by the stacking angle. (C) 2019 The Author(s)

Poling optical fibers with UV lamp
- 2019
-
Ingår i: Conference on Lasers and Electro-Optics OSA Technical Digest (Optical Society of America, 2019), paper SM2L.5. - : OSA - The Optical Society. - 9781557528209
-
Konferensbidrag (refereegranskat)abstract
- Silicate fibers with internal electrodes are optically poled without a laser by side-exposure to radiation from a UV tubular lamp. Electrooptic coefficients χ(2) ~ 0.04 pm/V and Vπ = 810 V are obtained.

-
Ingår i: Conference on Lasers and Electro-Optics. - : IEEE. - 9781943580576
-
Konferensbidrag (refereegranskat)abstract
- We combine for the first time a mid-infrared optical frequency comb Fourier transform spectrometer with cantilever-enhanced photoacoustic detection and measure high-resolution broadband spectra of the fundamental band of methane in a few milliliter sample volume.

Coherent Temporal Phase Transfer in Backward Wave Parametric Oscillator at 1.4 mu m
- 2019
-
Ingår i: 2019 CONFERENCE ON LASERS AND ELECTRO-OPTICS (CLEO). - : IEEE. - 9781943580576
-
Konferensbidrag (refereegranskat)abstract
- The frequency modulation transfer property of a backward wave optical parametric oscillator is employed to generate compressed near-IR pulses at 1.4 mu m with 1.3ps duration. Limitations to the linear frequency modulation transfer in BWOPO are investigated.
