Research Abstract

The fastest known operation of all-optical flip-flop memory was experimentally demonstrated using a 980-nm polarization bistable vertical-cavity surface-emitting laser(VCSEL). All-optical flip-flop operation was achieved at a record low bias current of 0. 85 mA using a VCSEL with an oxidation confinement structure. The memory operation was also achieved for 12. 5 Gb/s RZ signals in the 1. 55μm wavelength range. 1. 55μm pigtailed modules of the optical memory were successfully constructed.
