Abstract:
An optical device comprising:at least one optical substrate having formed thereon at least one waveguide having a center which lies in a waveguide plane; a base substrate onto which said at least one optical substrate is fixed and defining at least one optical fiber positioning groove; at least one optical fiber fixed in said at least one optical fiber positioning groove on said base substrate, whereby a center of said at least one optical fiber lies in a plane which is substantially coplanar with said waveguide plane; and at least one optical module, precisely positioned onto said base substrate and fixed thereto by means of side mounting blocks which are adhered to said at least one optical module by a thin layer of adhering material on a first surface of each of said side mounting blocks and are adhered to said at least one base substrate by a thin layer of adhering material at a second surface of each said side mounting blocks, said second surface being not parallel to said first surface, thereby to preserve precise mutual alignment of said at least one module and said at least waveguide.
