Abstract

We have made cross-talk measurements on our U-groove isolated phntodiode array by two independent techniques, the electrical measurement and the laser scanning method. These two methods are shown to correlate with each other. 'Vie cross-talk between two adjacent pixels of the U-groove isolated array was below 5x10^-4, which compared favorably to the value of 10^-1 for the conventional diffusion junction photodiode array. Also the effective diffusion length of the photogenerated carriers was measured to be 10 μm in the N-region and 6 μm in the top P-region. The advantages of the detector isolation technique for optical signal processing is presented.
