OPTICAL ISOLATOR WITH PRINTED CIRCUIT BOARD ISOLATION

摘要

An optical isolator (100) is provided. The optical isolator includes a printed circuit board (106) having a first surface (114) and a second surface (122) opposite the first surface. The printed circuit board (106) has a recess (110) extending only partially through the board (106). The first photoelement (104) has an active surface and is mounted relative to the first surface (114) of the printed circuit board. A second photoelement (102) has an active surface and is mounted relative to the second surface (126). The second photoelement (102) is configured to interact with the first photoelement (104). At least one of the first and second photoelements has its active surface disposed at least partially in the recess (110). A portion of the printed circuit board (106) is interposed between the first and second photoelements (104, 102).
