28-Gbps interconnect based on a plastic optical engine providing reduced modal dispersion Optics Communications, vol. 455, no. 124543, September 12, 2019
Abstract
A plastic optical engine that reduces modal dispersion was proposed and implemented for a 28-Gbps
interconnect.
its dependence on the angular distribution of the focused beam for a transmitter was examined.
The beam coupler was designed using two focused beam numerical apertures (FNAs) for transmitter.
The modal dispersion of the smaller FNA was superior to the larger FNA by 6.2 ps at the backshell temperature
of 75 ◦C for a 150-m OM3 fiber.
The manufactured optical engine with smaller FNA supported effective fiber
bandwidth for error-free data transmission over a 150-m-long OM3 fiber at 28 Gbps.
Decreasing the FNA suppresses modal dispersion, thus enabling the use of longer OM3 fibers.

Alignment tolerance slim optical interconnect for on-board interconnections IEEE/OSA Journal of Lightwave Technology, vol. 34, no. 3, February 1, 2016
Abstract
A four-channel slim optical interconnect is proposed and realized, featuring relaxed structural tolerance along with
pas- sive alignment.
A compact micro-optic beam coupler in plastic, in which a prism and lens are integrated with
a plastic optical fiber (POF) guide in a single body, is commonly incorporated in the transmitter (Tx) and
receiver (Rx).
A pair of finely controlled reference holes is created in a printed circuit board (PCB),
onto which a vertical cavity surface emitting laser (VCSEL) and photodetector (PD) are mounted.
The optical coupling for VCSEL-to-POF and POF-to-PD was meticulously performed via the pick-and-place scheme
in a cost effective manner, through the mediation of the beam coupler in conjunction with the reference holes.
For the manufactured slim interconnect, the effective thicknesses of the Tx and Rx modules were only 1.43 mm.
The achieved 3-dB alignment tolerances were 28 and 46 μm for the VCSEL and PD, respectively. The proposed
optical interconnect was finally demonstrated to deliver high speed video data at 5.4 Gb/s with high fidelity.

Ribbon POF based HDMI2.1 AOC incorporating and encapsulated optical engine POF 2018 Conference, Seattle, WA, USA, Sept. 4-6, 2018, paper no. 15
Abstract
A HDMI 2.1 AOC based on an encapsulated optical engine was proposed and realized featuring a high performance
and independent for an ambient temperature utilizing 4 channels ribbon POF.
The designed optical engine constituted on a beam coupler, ribbon POF, VCSEL, and PD.
The performance of the manufactured optical engine was observed to be error-free overnight.
The proposed optical engine could successfully cope with 27-1 PRBS signal and a data rate of as fast as 12 Gbps.
