CAVITY STRUCTURE AND METHOD OF CAVITY STRUCTURE FOR OPTICAL DEVICE, AND OPTICAL DEVICE

摘要

PPROBLEM TO BE SOLVED: To provide a cavity structure for an optical device which can be manufactured without previously forming a separating groove, and employs a configuration where optical components are placed, and to provide a method of manufacturing the cavity structure for an optical device. PSOLUTION: The cavity structure 1 for an optical device is provided with a first terminal 112 formed by alternately laminating insulating layers 11, 13, 15 and metallic layers 12, 14, 16, formed on a mounting surface to be mounted on a wiring board, and electrically connected to the wiring board; a cavity 2 having a substantially rectangular opening 2a on the center on the top surface; and an optically transmissive member placing portion 15a which is formed on the top surrounding the opening 2a and on which an optical transmissive member 124 for transmitting a light received or emitted by an optical element chip 121 is placed. The portion 15a is a coarsened surface of a insulating layer 15. PCOPYRIGHT: (C)2007,JPO&INPIT
