These cells are amacrines and ganglion cells. The main scheme of the authors' configuration is shown in a figure. These two types of cells, as well as some of their possible interconnections, have been implemented with the authors' previously reported optical-processing element. As it has been shown, the authors' logic structure is able to process two optical input binary signals, being the output two logical functions. Moreover, if a delayed feedback from one of the two possible outputs to one or both of the inputs is introduced, a very different behaviour is obtained. Depending on the value of the time delay, an oscillatory output can be obtained from a constant optical input signal. Period and length pulses are dependent on delay values, both external and internal, as well as on other control signals. Moreover, a chaotic behaviour can be obtained too under certain conditions date: 1994 date_type: published publisher: Institute of Electrical and Electronics Engineers official_url: http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=586940 id_number: 10.1109/LEOS.1994.586940 full_text_status: public pres_type: paper publication: Lasers and Electro-Optics Society Annual Meeting, 1994.
