A method for forming a micro-optical switch component includes providing a semiconductor substrate having a surface. An opto-electronic device is integrated into the semiconductor substrate at a site. A pedestal of microlens material is formed on the semiconductor substrate surface at the site of the opto-electronic device. The pedestal extends from the semiconductor substrate surface and has a top surface spaced apart from the semiconductor substrate surface. A print head is provided and contains an optical fluid which is hardenable and capable of serving as a micro-optical element. The printhead includes an orifice from which micro-droplets of the optical fluid are ejected in response to control signals. Optical fluid is deposited onto the top surface of the pedestal to thereby form a micro-optical element on the pedestal.

Method for producing a fiber optic switch

A low cost digitally operated dispenser apparatus and method of operation and construction is obtained by combining flat sided, preferably rectangular tubular capillary tube having an orifice, with a flat elongated strip of piezoelectric material. Microdroplets are dispensed from an internal chamber within the capillary tube, or a separate feed supply, upon application of voltage pulses through electrodes connected to conductive layers on the piezoelectric material. The piezoelectric strip may be parallel to the flat capillary tube or perpendicular to it. On a variation, a fixture can be used to improve performance in combination with the capillary tube and piezoelectric strip. A standoff strip allows the piezoelectric operator to be thermally isolated from a flat rectangular capillary tube.
