Konferensbidrag (refereegranskat)abstract
- We use the cost-effective APM technique to increase the non-linear tolerance of NRZ-OOK, and we demonstrate, in a recirculating loop experiment, the transmission over 2800 km SSMF of 16 NRZ-OOK 40 Gb/s channels with 100 GHz spacing.

-
Konferensbidrag (refereegranskat)abstract
- We demonstrate a novel technique for locking and tuning of a near-degenerate OPO using a transversely chirped Bragg grating. The signal tuning range was 997-1016 nm and the maximum signal energy was 0.7 mJ.

Transient electromagnetically induced transparency in InGaAs quantum dots
- 2008
-
Ingår i: 2008 Conference On Lasers And Electro-Optics & Quantum Electronics And Laser Science Conference. - 9781557528599 ; , s. 3597-3598
-
Konferensbidrag (refereegranskat)abstract
- Electromagnetically induced transparency (EIT) based on exciton spin transitions is observed in InGaAs quantum dots. Inhomogeneous broadening of the quantum dot ensemble, detrimental for EIT, is effectively reduced by using spectrally narrow pulses.
