MULTI-CHANNEL MACH-ZEHNDER INTERFEROMETER TYPE OPTICAL CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a multi-channel Mach-Zehnder interferometer type optical circuit in which two subjects of high density integration and influence elimination of heat interference are simultaneously solvable.;SOLUTION: The Mach-Zehnder interferometer type optical circuit is constructed by arranging a groove 7 and an heat insulation wall 8 between the Mach-Zehnder interferometer type optical circuits of respective channels, a plurality of which being present on a chip, in the multi-channel Mach-Zehnder interferometer type optical circuit. Thereby heat emitted from the adjoining Mach-Zehnder interferometer type optical circuit is effectively suppressed and the heat interference is suppressed.;COPYRIGHT: (C)2005,JPO&NCIPI
