摘要： Embodiment of present invention provide a wavelength division multiplexing (WDM) module. The WDM module includes a substrate having a first side and a second side opposing the first side, wherein the first side includes a transpassing region coated with an anti-reflective (AR) film and a reflective region coated with a high-reflective (HR) film, and the second side includes multiple ports of optical paths; multiple WDM filters attached to the multiple ports at the second side of the substrate, wherein surfaces of the WDM filters attached to the substrate are coated with WDM films; and at least one reflector attached to the second side of the substrate in a space between the multiple WDM filters, wherein the reflector has a first surface attached to the substrate and a second surface, opposing the first surface, that has a convex shape and coated with a high-reflective (HR) coating.

摘要： Embodiment of present invention provide a micro-optics module. The module includes a glass body of pentagon shape having five side surfaces including an upper side surface, a left side and a right side surface next to the upper side surface, a lower side surface next to the left side surface, and a 5th side surface next to and between the lower side surface and the right side surface. The glass body is adapted to, upon incident of a first optical signal at the left side surface, cause the first optical signal to propagate toward and exit the glass body at the right side surface and, upon incident of a second optical signal at the right side surface, cause the second optical signal to reflect back at the left side surface; reflect back at the 5th side surface; and finally exit the glass body at the upper side surface.
