Intensity Noise Characteristics of Multimode VCSELs

Static Characteristics of VCSELs and PIN Photodiodes for Bidirectional Standard Multimode Fiber Transmission

We present the monolithic design, fabrication and static properties of 850 nm wavelength AlGaAs–GaAs-based transceiver chips with a stacked layer structure of a VCSEL and a PIN photodetector. Bidirectional data transmission via a single, two-side butt-coupled multimode fiber (MMF) is thus enabled. The approach aims at a miniaturization of transceiver chips in order to ensure compatibility with ...

Low Frequency Noise Characteristics of Multimode and Singlemode Laser Diodes

Greatly enhanced modulation response of injection-locked multimode VCSELs.

We report greatly enhanced modulation response of multimode vertical-cavity surface-emitting lasers (MM-VCSELs), for the first time, using optical injection locking. A 3-dB bandwidth of 38 GHz and 54 GHz resonance frequency are achieved using a MM-VCSEL with a 3 GHz free-running bandwidth. We show that transverse mode selection can be attained with optical injection locking through frequency an...

High Speed Characteristics of VCSELs

The high speed characteristics of Vertical Cavity Surface Emitting Lasers (VCSELs) for use in modern high bandwidth fiber optic networks is presented. An equivalent circuit model based on microwave network analyzer S 11 measurements is developed. The dynamic operation of multi-transverse mode VCSELs is also investigated. Experimentally, a laser with two orthogonally polarized modes is examined....

Optical Backplane Waveguides with 850 nm Wavelength Multimode VCSELs

An optical backplane concept based on polymer waveguides, well suited to overcome the communication bottleneck caused by conventional printed circuit boards is investigated. Attenuation coefficients are determined for several waveguides on different backplanes and it is shown that 10 Gbit/s data transmission at a bit error rate of 10 is possible both for waveguides of large (250 × 200 μm ) and ...
