Provided is a light emitting device and a method of manufacturing the same. Voltages are applied to the electrodes to produce a voltage gradient along the length of the ion source region. Thereafter, the TDGM processes the pattern dictionaries to automatically generate the transformation document. Devices made in such a way may be used in a wide variety of applications including incorporation into medical devices. 0 to about 10,000, a porosity of about 40% to about 85%, a density of about 0. The optical connector with memory function 3 of the present invention is characterized by a memory function capable of untouchably performing, from outside thereof, writing-in and reading-out of necessary information.
