## A selective determination of the carrier density and mobility of a two-dimensional electron or hole gas in HFET or MODFET samples can be performed by measuring the magnetic-fielddependent resistivity and Hall coefficient over a field range of 1 Tesla. This is achieved even in the presence of domi
A compact variable optical attenuator (VOA) driving by thermal actuating principle with dual shutters for single mode fibers is developed. The fabricated thermal actuator array is capable of achieving larger displacement with low applied voltage than traditional thermal actuator array. The designed
## Abstract A highβdynamicβrange variable optical attenuator (VOA) using a movable shutter, which moves in a tiltedβangle direction to the collimate fiber pair, is proposed. The VOA operates in the C+L band with the advantages low cost, high dynamic range of more than 50 dB, low insertion loss of 0
