Paper Abstract

We present the following results. Using an e-beam lithography we fabricate don a quartz substrate binary DOEs for the effective formation of individual Gauss-Hermite modes, (1,0), (1,1), (1,2) and (7,0). The transmission function of such DOEs is found to equal the signum function of the Hermite polynomial. Numerical simulation has shown that the binary signum DOEs are capable of generating first GH modes with a 64-72 percent efficiency. In real experiments such DOEs operate in agreement with theory and with satisfactory efficiency.
