OPTICAL PHASE MODULATOR - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18192791 Titled 'OPTICAL PHASE MODULATOR'
Simplified Explanation
The abstract describes an optical phase modulator that uses a rib structure with different types of materials to control the phase of light. The rib structure consists of an N-type rib portion and a P-type rib portion, which are connected to N-type and P-type slab portions respectively. This creates a PN structure in the cross-section of the rib. Additionally, a P-type third slab portion is connected to the N-type rib portion and an N-type fourth slab portion is connected to the P-type rib portion, creating a PNPN structure in the cross-section of the rib. These PN and PNPN structures are arranged alternately along the extending direction of the rib.
Original Abstract Submitted
An optical phase modulator includes a rib part extending in an extending direction. The rib part includes an N-type first rib portion and a P-type second rib portion arranged in a width direction to have a PN junction therebetween along the extending direction. An N-type first slab portion is connected to the first rib portion and a P-type second slab portion is connected to the second rib portion to provide a PN structure with the rib part in a cross-section having a normal direction along the extending direction. A P-type third slab portion is connected to the first rib portion and an N-type fourth slab portion is connected to the second rib portion to have a PNPN structure with the rib part in a cross-section having a normal direction along the extending direction. The PN structure and the PNPN structure are alternately disposed in the extending direction.
