We have developed an integrated micro-probe with improved detection efficiency for apertureless NSOM by using micromachining techniques; we call this probe a 'photocantilever'. A photocantilever is an integrated microcantilever with a pn-junction at its end; it is fabricated using micromachining techniques. It has achieve higher collection efficiency than conventional near-field scanning optical microscopy(NSOM) probes because the detector is placed close to the scatterer. Two new types of NSOM can be performed using this photocantilever: totally-internal-reflection-illumination-based NSOM and differential NSOM. Both provide NSOMs with high spatial resolution. The photocantilever enables apertureless NSOM with high collection efficiency and high resolution.
