Abstract
An optical circulator and an optical module are provided. The optical circulator includes a first polarization beam splitter member having a common optical port, a second polarization beam splitter member having an emittance optical port and at least two receiving optical ports, and a first polarization adjustment member. The two receiving optical ports respectively receive two linearly polarized light beams. The two linearly polarized light beams respectively pass through the second polarization beam splitter member, and sequentially pass through the first polarization adjustment member and the first polarization beam splitter member to be combined into a first combined light beam for being output from the common optical port. The common optical port receives a compound optical signal that passes through the first polarization beam splitter member to be split into another two linearly polarized light beams that are combined into a second combined light beam for being output.
