Abstract:
A silicon waveguide (110) comprising a waveguide core (118) that comprises a first positively doped region (111), also refers to as P1 region, vertically adjacent to a second positively doped region (112), also refers to as P2 region, The P2 region (112) is more heavily positively doped than the P1 region (111). A first negatively doped region (114), also refers to as N1 region, is vertically adjacent to a second negatively doped region (113), and also refers to as N2 region. The N2 region (113) is more heavily negatively doped than the N1 region (114). The N2 region (113) and the P2 region (112) are positioned vertically adjacent to form a PN junction. The N1 region (114), the N2 region (113), the P1 region (111), and the P2 region (112) are positioned as a vertical PN junction and configured to completely deplete the P2 region (112) of positive ions and completely deplete the N2 region (113) of negative ions when a voltage drop is applied across the N1 region (114), the N2 region (113), the P1 region (111), and the P2 region (112).
