Abstract
Microring resonator-coupled Mach-Zehnder interferometer (MRCMZI) is attractive for its applications in the field of all-optical switch, with low threshold, fast response speed and compact scale suitable for integration. The paper provides analytically and numerically investigation on optical pulse transmission characteristics of MRCMZI. The analytical formulations of dynamic process are derived in an easy-understood method of light beam tracing. These formulations can degenerate gradually to steady-state response when incident pulse becomes quasi-continuous wave (CW) or adequately broad with duration much more than cavity lifetime. For the coupled-microresonator system, several interesting signal processing tasks, such as optical differentiation, integration, pulse compression and trigger pulse generation, can be realized. Because of the complementarity between two output ports of MZI, the optical pulse differentiation and integration operations can be carried out synchronously at two output ports through optical interference between the reference light of direct-bus and the modulated light of coupled-microresonator bus. The interesting functions related to optical pulse shaping have potential applications in future all-optical communication.
