We demonstrate optical wireless transmission with two-dimensional (2D) beam-steering using an optical phased array (OPA). The OPA consists of 64-elements of electro-optic p-i-n phase shifters and thermo-optic tunable n-i-n grating radiators, employed

The tolerance of the optical components in the near-field recording (NFR) system is analyzed. The system uses a solid immersion lens (SIL) for near-field recording and an air bearing slider to maintain the near-field gap between the SIL and a magneto
