STUDY ON CHARACTERISTICS OF 1.3μm InGaAsP/InP DH LED WITH INTEGRATED LENS
Design and fabrication of 1.3nm InGaAsP/InP DH LED with a monolithic integral lens
which exhibits high-speed performance
have been presented.Dependences of operating characteristics
such as the coupled power
the far field radiation patterns and the cut-off frequency on the LED and fiber structure parameters
have been analyzed and applied to complete an optimal design. LED's coupled to graded fiber with 50μm core
0.2NA were fabricated at the wavelength of 1.3μm. A significant improvement has been achieved particularly in the cut-off frequency and the maximum value of 425MHz at 150mA has been realized.Remarkable improvement in the coupling efficiency is demonstrated.
