Abstract

We analyze the balanced homodyne detection technique in the detection of squeezed light, which is controlled by dither locking scheme. We discuss how the balanced homodyne detection efficiency influences the detected degree of squeezing. Also, fluctuation in the relative phase between the local beam and the squeezed light is discussed, since a little phase fluctuation would decrease the detected degree of squeezing greatly. Then, the dither locking technique is studied in detail, which is used to lock the relative phase between the local beam and the squeezed light. The simulation experiments and theoretically results show that the balanced homodyne detection technique and the dither locking scheme are efficient methods to get more accurate degree of squeezing in the preparation of the squeezed states of light.
