A fully coherent optical code-division multiple access (OCDMA) scheme that combines spectral phase encoding (SPE) and spectral line pairing to generate signals through heterodyne decoding is proposed. A simple balanced receiver performs sourceless heterodyne detection, canceling speckle noise and multiple-access interference (MAI). A 16 user 100% load… (More)
We present a scalable approach to optical time division multiplexing using a time lens. With simply a single device we demonstrate direct TDM to WDM conversion. Data rates up to 1.28 Tb/s are realized.
Utilizing a 6-mm-long hydrogenated amorphous silicon nanowaveguide, we demonstrate error-free (BER <; 10<sup>-9</sup>) 160-to-10 Gb/s OTDM demultiplexing using ultralow switching peak powers of 50 mW. This material is deposited at low temperatures enabling a path toward multilayer integration and therefore massive scaling of the number of devices in a… (More)
We experimentally demonstrate and analyze through simulation an OTDM→WDM serial to parallel converter that fully extracts all 1610-Gb/s WDM channels from a 160-Gb/s OTDM data stream in a single device using an optical Fourier processor. The device operates by dispersing a pump pulse across all OTDM channels and using the nonlinear optical process of… (More)
We have developed and tested a compact free-hand microsurgical tool-concept based on CP-OCT distance-sensor and 1-D actuation, which is capable of tracking the surface of surgical target tissue and compensating tool-tissue relative-motion with micrometer resolution.
