Abstract:

In this work, we have built 3 control circuit boards running at 2.5 Gbs. These include a cell delineation circuit board, a VCI over writing circuit board, and a cell synchronizer control circuit board, and a cell synchronizer control circuit board. We also design and fabricate a 1x2 semiconductor optical amplifier SOA broadband space switch. Multiwavelength signal switching using the fabricated switches is demonstrated. We also build the VCI overwriting and cell synchronization optical systems using both LiNbO3 switches and the fabricated switches. We have completed the interfaces of the optical systems with the control circuit boards and finally demonstrated the proposed photonic ATM front end processor at 2.5 Gbs.
