TEM10 homodyne detection as an optimal small displacement and tilt measurements scheme
arXiv:quant-ph/0607142 · doi:10.1103/PhysRevA.74.053823
Abstract
We report an experimental demonstration of optimal measurements of small displacement and tilt of a Gaussian beam - two conjugate variables - involving a homodyne detection with a TEM10 local oscillator. We verify that the standard split detection is only 64% efficient. We also show a displacement measurement beyond the quantum noise limit, using a squeezed vacuum TEM10 mode within the input beam.
