.Design of multimode interference optical switches with area modulation[J].Optoelectronics Letters,2007,3(4):248-250 Design of multimode interference optical switches with area modulation PANJian-xia SUNYMing TANGZhuo-qi [1]Elecfmnfc Institute,HangzhouDianziUniversity,ofElectronicScienceandTechologyHangzhou3J00J8,China [2]CollegeofEngineeringandTechnology Shenzhen University,Shenzhen518060,China Abstract:       Based on the self-imaging effect, multimode interference (MMI) optical switches with area modulation were proposed. The field transfer matrix was introduced to analyze the MMI switches. As an example, the phase modulation parameters of a 3 × 3 MMI switch for different switching cases were obtained by solving the field transfer equation. And the finite-difference beam propagation method (FD-BPM) was used to confirm the analytical results. Hits: 3498 Download times: 191 View Full Text    Download reader
