| Submission declined on 15 August 2025 by Dan arndt (talk). This submission appears to read more like an advertisement than an entry in an encyclopedia. Encyclopedia articles need to be written from a neutral point of view, and should refer to a range of independent, reliable, published sources, not just to materials produced by the creator of the subject being discussed. This is important so that the article can meet Wikipedia's verifiability policy and the notability of the subject can be established. If you still feel that this subject is worthy of inclusion in Wikipedia, please rewrite your submission to comply with these policies.

Bakman Technologies LLC is an American company that designs and manufactures frequency-domain terahertz (THz) spectrometers and photonic components.
History
[edit]In December 2014, as part of a general corporate restructuring and change of board control, several divisions of Emcore Corporation were divested and spun off. The Advanced Photonics Division, which included their Terahertz (THz) products and technology, was sold to Bakman Technologies.
Technology and applications
[edit]The PB7000 series of THz spectrometers employ coherent frequency-domain THz spectroscopy photomixing. This makes the technology suitable for various applications including: determining detection limits for trace isotopologues,[1] performing real-time airborne gas analysis from a consumer drone,[2] examining electronic and magnetic materials at low temperatures,[3] reducing Fabry–Perot interference and system dispersion in continuous-wave THz coherence measurements,[4] testing silicon gradient refractive index lenses for millimeter-wave radiometers,[5] testing tunable graphene-based metamaterial THz modulators,[6], Developing modulation-capable silicon waveguides for on-wafer THz interconnects,[7] fabricating affordable THz components via 3D printing,[8] advancing broadband impedance matching to two-dimensional materials,[9]
