Crosstalk Characteristics and Performance of VCSEL Array for Multicore Fiber Interconnects

This paper investigates the crosstalk characteristics of a dense two-dimensional 6-channel 850-nm VCSEL array designed for multimode multicore fiber (MCF) interconnects. Interchannel optical, thermal, and electrical crosstalk is measured and found to not affect channel integrity and receiver sensiti...

Summary:This paper investigates the crosstalk characteristics of a dense two-dimensional 6-channel 850-nm VCSEL array designed for multimode multicore fiber (MCF) interconnects. Interchannel optical, thermal, and electrical crosstalk is measured and found to not affect channel integrity and receiver sensitivity when transmitting data over an MCF with a fiber fan-out. We demonstrate error-free data transmission (bit-error-ratio <;10 -12 ) up to 40 Gb/s/channel over an MCF, which shows promise for an aggregate capacity of 240 Gb/s over a single fiber in a future link.
