Konferensbidrag (refereegranskat)abstract
- Backward-wave OPO with forward mid-infrared idler and backward signal generation is demonstrated in 500-nm-periodicity PPRKTP. The output energy of 2.39mJ and efficiency of 46.4% is obtained. This design has potential for broad tunability in mid-infrared.

Fractal superconducting nanowire single-photon detectors with low polarization sensitivity
- 2018
-
Ingår i: Optics InfoBase Conference Papers. - : Optical Society of America. - 9781557528209
-
Konferensbidrag (refereegranskat)abstract
- We demonstrated a fractal superconducting nanowire single-photon detector and achieved 42% device efficiency and 1.04 polarization sensitivity. The low polarization sensitivity can be maintained for higher-order spatial modes in few-mode optical fibers.

Ingår i: 2018 Conference on Lasers and Electro-Optics (CLEO). - : IEEE. - 9781943580422
-
Konferensbidrag (refereegranskat)abstract
- We retrieve high precision absorption and dispersion spectra of the 3v(1)+v(3) band of CO2 from direct measurement of cavity transmission modes using an optical frequency comb and a mechanical Fourier transfolin spectrometer with sub-nominal resolution.

-
Konferensbidrag (refereegranskat)abstract
- By combining Faraday rotation spectroscopy with an optical frequency comb Fourier transform spectrometer, we measure background- and calibration-free spectra of the entire Q- and R-branches of the fundamental band of nitric oxide at 1850-1920 cm-1.

Electrically pumped hybrid III-V/Si photonic crystal surface emitting lasers with buried tunnel-junction
- 2018
-
Ingår i: Optics InfoBase Conference Papers. - : Optical Society of America. - 9781557528209
-
Konferensbidrag (refereegranskat)abstract
- We report here an electrically pumped hybrid photonic crystal surface emitting laser (PCSELs) on silicon. The laser cavity consists of a transferred InGaAsP multi-quantum well (MQW) heterostructure membrane, printed on a single layer silicon photonic crystal (Si-PC) cavity. A buried tunnel-junction (BTJ) has been employed in the MQW structure for efficiency charge injection. Single mode emitted spectrum was achieved at 1504 nm for a large area laser in the continuous-wave (c.w.) mode under room temperature operation.

Konferensbidrag (refereegranskat)abstract
- We demonstrate all-optical intensity modulation in integrated PMMA optical waveguides doped with silicon quantum dots. The 1550 nm probe signal is absorbed by free carriers excited in silicon quantum dots with 405 nm pump light.

7×149 Gbit/s PAM4 transmission over 1 km multicore fiber for short-reach optical interconnects
- 2018
-
Ingår i: Optics InfoBase Conference Papers. - : Optics Info Base, Optical Society of America. - 9781557528209
-
Konferensbidrag (refereegranskat)abstract
- We transmit 80 Gbaud/λ/core PAM4 signal enabled by 1.55 μm EML over 1 km 7-core fiber. The solution achieves single-wavelength and single-fiber 1.04 Tbit/s post-FEC transmission enhancing bandwidth-density for short-reach optical interconnects.
