The aim of this dissertation is to fabricate an optical transceiver based on Si-bench technology for light peak application. The transceivers are composed of hybrid integration of the vertical cavity surface-emitting lasers (VCSEL), photo diodes and multi-mode fibers (MMF) on the Si optical bench using V-groove and U-groove structures. We are able to passively align VCSEL to MMF and photo diode to MMF because of the accurately-aligned characteristic of V-groove. The 45-degree-angled fibers with mirror coating are used to bend the directions of both the incoming and outgoing lights to the photodiode and the MMF. The simulations showed that the optical losses of the transceiver are less than 10 dB when the distance between VCSEL and MMF is 250μm.The measured optical losses between transmitting module and receiving module are less than 12 dB.
Key words: Light Peak、optical transceiver、Si-bench、accurately-aligned
