Abstract
Effect of I/Q imbalance on multi-level modulated signals interleaved with reference light is analytically investigated. We show that received signals are degraded by the I/Q imbalance resulting from optical-frequency misalignment between a light source and an optical delay interferometer. Then, quality of the received signals is evaluated by numerical simulations.
