32 Gb/s transmission experiments using high speed 850 nm VCSELs
- 2009

Ingår i: Conference on Lasers and Electro-Optics (CLEO). - 2162-2701. - 9781557528698 ; , s. 1-2

Konferensbidrag (refereegranskat)abstract
- We demonstrate error free transmission at bit rates up to 32 Gb/s at room temperature and 25 Gb/s at 85degC using a 9 mum oxide aperture 850 nm VCSEL. The VCSEL design is optimized for high speed operation by minimizing parasitics, reducing self-heating, and using strained InGaAs quantum wells to improve differential gain.

-
Konferensbidrag (refereegranskat)abstract
- We use an all-optical method to characterize the modulation bandwidth of a DFB-EA designed for 100 Gb/s Ethernet. In a large-signal wavelength conversion set-up, we show the device has an all-optical bandwidth of 83 GHz.

-
Konferensbidrag (refereegranskat)abstract
- A single-plane FFT-based algorithm which optimizes a defocused field corresponding to a desired spatial configuration of focused spots is presented. The defocused target field allows for grid-free spot positioning in 2D and 3D.

-
Konferensbidrag (refereegranskat)abstract
- VBGs can efficiently be used to mitigate the spectrally broad output from cryogenically cooled Yb-fiber lasers. We extract 11.5-W of output power in spectral window of less than 0.4-nm with 14.5-W of launched pump light.

-
Konferensbidrag (refereegranskat)abstract
- We have investigated design criteria for calculation of computer generated holograms, aiming to reduce the deterioration of the spot pattern during SLM updates. A modified Gerchberg-Saxton algorithm that efficiently minimizes unwanted intensity fluctuations is introduced.
