摘要:
A method for glass-blowing on a microscopic level includes the steps of defining a plurality of microholes in a wafer, disposing a sheet of thermally formable material onto the wafer covering the microholes, heating the sheet of thermally formable material until a predetermined degree of plasticity is achieved, applying self-induced fluidic pressure by expansion of the heated trapped gas in the microholes to the sheet of thermally formable material, while the sheet is still plastic, and simultaneously forming a plurality of blown micro-objects in the sheet on the wafer by means of continued application of pressure for a predetermined time.
摘要:
An atomic magnetometer that simultaneously achieves high sensitivity, simple fabrication and small size. This design is based on a diverging (or converging) beam of light that passes through an alkali atom vapor cell and that contains a distribution of beam propagation vectors. The existence of more than one propagation direction permits longitudinal optical pumping of atomic system and simultaneous detection of the transverse atomic polarization. The design could be implemented with a micro machined alkali vapor cell and light from a single semiconductor laser. A small modification to the cell contents and excitation geometry allows for use as a gyroscope.
