Japanese Patent JP3358770

B2

A light control substance having a negative input-output characteristic is used to invert optical signals. The light control substance is an absorbing substance and has a multi-level energy structure such that ground state absorption occurs between a ground level (E1) and a level (E3) higher than the ground level (E1) and excited state absorption occurs between an excited level (E2) and a level (E4) higher than the excited level (E2). At a specific wavelength, a variation DELTA Iout in the intensity of output light and a variation DELTA Iin in the intensity of input light satisfy the following equations: $$ where\; alpha\; 1\; is\; an\; absorbance\; of\; the\; ground\; state\; absorption,\; alpha\; 2\; is\; an\; absorbance\; of\; the\; excited\; state\; absorption,\; and\; gamma\; is\; a\; ratio\; of\; electrons\; relaxing\; from\; the\; level\; (E3)\; higher\; than\; the\; ground\; level\; (E1)\; to\; the\; exited\; level\; (E2).\; As\; a\; result,\; the\; value\; of\; DELTA\; Iout/\; DELTA\; Iin\; becomes\; negative.\mathop{\mathrm{image}}$$
