I searched the EDN Mag database and got this answer:

"    The following matches were found in the EDN Archives for the search on
OPTICAL ISOLATOR
    AND WATTS. The results are ordered with the closest match listed first.
Higher scores indicate better
    matches.
    The search engine found 0 item(s) matching the search criteria"

Their database only goes back to Jan 1994.  Can you pls. give us more info?
