+// Optical AND Gate Implementation
+// 
+// This module simulates an optical AND gate using Verilog.
+// In optical computing, an AND gate can be implemented using:
+// - Nonlinear optical materials (e.g., MoS2, GaAs)
+// - Two input laser beams with binary encoding (0=no light, 1=light present)
+// - The output is light only when both inputs have light (logical AND)
+//
+// Physical Implementation:
+// - Input A and B are represented as optical signals (light intensity)
+// - The gate uses nonlinear optical effects where two beams interact
+// - Output light is produced only when both inputs are present
+// - This can be achieved through four-wave mixing or cross-phase modulation

+// Physical Implementation:
+// - Input A and B are represented as optical signals (light intensity)
