Abstract:
A phased array device having a central wave length, said device comprising:a first member having a planar input area;a second member having a planar output area;a microguides array arranged between said input and output areas;input means for applying a light beam to said planar input area; andoutput means for outputting a light beam from said planar output area, at least one of said members being formed of two parts, one of said parts including at least a portion of one of said planar input and output areas and its respective input or output means and the other part of said one member including the complementary portion of said one of said planar input and output areas, said microguides array and said other member, whereby said central wave length of said device may be adjusted by adjusting said two parts of said one member with respect to each other.
