| | 07-0068 requested a new industry for photonics. The industry would include photonic waveguides and photonic integrated |
| | circuits. While there are technical differences in the production of integrated circuits and photonic integrated circuits, the ECPC |
| | feels that the current production function-oriented industries identified in Industry Group 3344, Semiconductor and Other |
| | Electronic Component Manufacturing, are appropriate. Index items for photonic integrated circuits and for silicon wave guides |
| | should be added for Industry 334413, Semiconductor and Related Device Manufacturing, and a cross reference for silicon |
| | wave guides to Industry 334413 should be added in Industry 334419, Other Electronic Component Manufacturing. |
