Optical memory with 10Gbps data rate using 2-D VCSEL array

摘要

An optical armory disk head far situ-high data transfer rate using parallel two dimensional pyramidal prism probe (ppp) and VCSEL array bat hers attracting en act interest for the data storage in sear falser Betzig and coworkers demonstrated as optical recording possibility by optical scanning microscope (NSOM) and suggested 100GB data storage capacity. Since the total efficiency of the near-field fiber probe used is however Ins law to write the bits on the surface of the optical disk with higher bit rate than several kbps, realizing 2-D probes with higher throughout efficiency sting semiconductor pyramidal prism probes (PPP) conjunction with proposed a terabyte optical memory system using a VCSEL array to very important. For realizing high density/speed sear-field optical recording, new near-field probes sting GaP (n=3.3 @ λ=650nm) protruded array and alto Si probe array have been successfully fabricated with high throughout efficiency.
