%X We present an experimental study on the microstructured-fibre (MSF) based heralded single photon source (HSPS) at 1.5μm. The preparation efficiency is measured to be 8.7% under room temperature. The analysis of the experimental results shows that the preparation efficiency can be improved up to 22.9% by the Raman noise suppression with fibre cooling under the experimental setup parameters. Further efficiency improvement could be achieved by improving the collection efficiency and reducing dark counts of single photon detectors (SPDs). The experimental results and analysis show great potential applications of the MSF in high efficient HSPSs.
