I need to a single mode 1550 optical circulator at my lab. I have a varied supply of components, but no circulator. Any idea how I can make one myself? Perhaps using coupler and isolator?

If you didn't mind throwing away 1/2 the power you could make one with beam splitters and isolators. But maybe just buy one from Thor labs.. ~$600.
