Zusammenfassung:Active optical alignment of plastic chip-scale-package laser and photo detecting diode devices is provided by use of an active probe to make alignment structures, such as précising holes, that are used to align the optical device into a transmit/receive module. An optical connector, such as an optical fiber, transmits light to, or receives light from, the optical device. Using an electrical contact, laser diode devices are lighted or photo detecting diode devices are electrically interfaced. The optical connector steps to, locates and contacts each optical device on a fabricated frame of multiple devices. The optical connector is manipulated to an optimal coupling position where the best signal, either optical or electrical, is obtained. An optimal position for making the précising holes, e.g., using a machining laser, is determined as an offset from the optimal position of the optical connector.
