    摘要: A magnetic field measuring head comprises the following elements integrated into one and the same substrate: a light source, a light guide insensitive to the magnetic field, a layer of magnetic material which, when plunged into a magnetic field to be measured, causes the rotation of the plane of polarization of the light coming from the source, and a device to measure the rotation of the plane of polarization of the light.

    摘要: A type-II InAs/GaSb superlattice photodiode for optimizing quantum efficiency without reducing the differential resistance area product at zero bias. The photodiode features a GaSb: Be buffer, a In/GaSb: Be superlattice, a p-type doped π region, a InAs: Si/GaSb doped region, and a InAs: Si doped contact layer. The In/GaSb: Be superlattice and InAs: Si/GaSb doped region each having a thickness about two times greater than the thickness of the GaSb: Be buffer. The photodiode in one embodiment featuring a composition of InAs and GaSb with InSb forced interfaces, the composition suitable for being grown on GaSb wafers with a molecular beam epitaxy reactor. A method of optimizing quantum efficiency in a type-II InAs/GaSb superlattice photodiode having a 100% cutoff wavelength around 12 μm is further provided herewith.
