We present two gigabit/s spectral-amplitude-coding O-CDMA techniques that use coherent multi-frequency light. The techniques achieve high beat-noise tolerance by either employing multi-frequency self-homodyne detection or using spectral M-ary ASK based on electrical-domain spatial-code spreading.
We propose and demonstrate phase-matched OCDM transmission based on multi-frequency self-homodyne detection. The feasibility is verified based on experiments using a developed PLC-LN module at the bit rate of 1.5 Gbit/s.
We fabricated a 50-mm-long ZnO-doped quasi-phase-matched LiNbO ridge waveguide by employing the direct bonding and dry etching techniques. We obtained a second-harmonic generation conversion efficiency of 2400%/W and a second-harmonic output power of 148 mW with a pump power of 160 mW. We demonstrated 1.55-m-band wavelength conversion based on a cascade scheme. A parametric conversion gain of 5 dB...
A novel waveguide periodically poled lithium niobate crystal for difference frequency generation in the mid-IR spectral region at 3.52 mum is characterized. High mid-IR power of 15 mW and a conversion efficiency of up to 19%/W have been obtained.
We achieved apodization in a quasi-phase-matched wavelength converter. The new design provides an increased bandwidth and a flat phase-matching response with high conversion efficiency. We demonstrate widely tunable 3.4-μm-band difference frequency generation in a LiNbO 3 waveguide device.
We fabricate wavelength conversion modules for 3.4 and 2.3 micron difference frequency generation using the V-groove connection technique. Both modules exhibit high output powers of over 3 mW.
