Quasi-single mode VCSELs for longer-reach multimode fiber optical interconnects
- 2014
-
Ingår i: Summers School on Optical Interconnects, 3-6 June 2014, Thessaloniki.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Longer-reach (>300 m) optical interconnects are needed asdatacenters grow ever larger. Today the reach of 850 nmVCSEL-based optical interconnects is mainly limited by fiber dispersion. By reducing the spectral width of the VCSEL, the effects of fiber dispersion may be reduced, effectively increasing the error-free transmission distance.

20 Gbit/s data transmission over 2 km multimode fibre using 850 nm mode filter VCSEL
- 2014

Tidskriftsartikel (refereegranskat)abstract
- Error-free data transmission over 1.3 and 2 km multimode fibre at 25 and 20 Gbit/s, respectively, is demonstrated using a high-speed, single-mode, 850 nm vertical-cavity surface-emitting laser (VCSEL) with an integrated mode filter. This result represents a bitrate-distance product of 40 Gbit/s km, a new record for multimode fibre VCSELbased interconnects.

40 Gb/s data transmission over a 1 m long multimode polymer spiral waveguide

Ingår i: European Conference on Optical Communication, ECOC 2014; Cannes; France; 21 September 2014 through 25 September 2014. - 9782954944401 ; , s. Paper P.4.7-
-
Konferensbidrag (refereegranskat)abstract
- We report record error-free data transmission of 40Gb/s over a 1m-long multimode polymer spiral waveguide. The waveguide imposes no significant transmission impairments in the link despite its highly-multimoded nature and long length, demonstrating its potential in high-speed board-level optical interconnections.

Ingår i: Conference Digest - IEEE International Semiconductor Laser Conference. - 0899-9406. - 9781479957217 ; , s. 78-79
-
Konferensbidrag (refereegranskat)abstract
- The dependence of large signal VCSEL dynamics on damping is studied through time-domain measurements of turn-on transients and timing jitter for VCSELs having K-factors from 0.1 to 0.4 ns.

Optimum Damping Level for High-Speed Large Signal VCSEL modulation
- 2014
-
Ingår i: Optics and Photonics in Sweden, 11-12 Nov. 2014.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The commercial optical interconnects used in datacenters and high performance computers have recently been pushed to data rates of 25-28 Gbps. Near future standards will require even higher data rates and further work to increase the speed is therefore necessary. Typically the 850 nm vertical-cavity surface-emitting laser (VCSEL) is employed as light source in such optical interconnects, due to its low-cost fabrication and excellent high-speed properties at low drive currents.Previously, we have shown that a reduction of the damping of the VCSEL small signal modulation response can increase the modulation bandwidth (BW) and that there exists an optimum damping for maximum BW. This allowed us to demonstrate a record-high small signal modulation BW of 28 GHz and error-free [bit error rate (BER)
