The TRBS model of respiratory physiology is based on the water dissociation by low power radiation, emitted from CO2 to hemoglobin as organic semiconductor. The unit is composed of three modules: (a) The Tunable Microcavity Module—in the terminal bronchioles, (b) The Compressor Module—in the respiratory bronchioles, (c) The Reservoir Module—in the alveolar sacs. Two types of optical processes lead to energy amplification: Spontaneous Emission and Thresholdless Emission in a Tunable Microcavity. The tunable microcavity is covered by a surfactant that serves as a multilayer reflective surface. The vagal nerve innervates the microcavity and the muscles contract (Q factor). The compressor controls CO2 cooling. Collisions of colder CO2 molecules with warmer homonuclear N2 molecules, excited to a vibrational metastable level, which leads to the population inversion via vibrational excitation of the CO2 that is necessary for microcavity lasing. The vibrational modes lattice transports energy to cells and genome.
