Development of Polarization Diversity Sampling Head Unit using Organic AANP Crystals and 160 Gb/s Far-end Waveform Measurement

抄録

We have previously developed a turn-key-ready OSO (optical sampling oscilloscope) system with a jitter of 0.2 ps rms and a resolution of 1 ps. Recently, we studied the characteristics of an AANP (2-adamantylamino-5-nitropyridine) crystal, which is the newest organic crystal for achieving a high-sensitivity optical sampling head unit for the OSO system. We developed a polarization-independent sampling head with a high sum-frequency conversion efficiency over the C-L bands using the AANP crystals.
This paper reports the characteristics of the AANP crystal and the developed configuration of a polarization-independent optical sampling head unit with AANP crystals. Furthermore, we demonstrate 160 Gb/s far-end measurement using the OSO system with the developed sampling head unit.
