This book is a sequel of The Physics of Quantum Well Infrared Photodetectors (1997), which covered the basic physics of QWIPs. In the intervening 27 years, QWIP properties pertinent to infrared detection are much better understood, and QWIP technology has become a mainstream, widely deployed infrared technology. The main progress is the ability to know the QWIP absorption quantum efficiency quantitatively through rigorous electromagnetic modeling. The lack of theoretical prediction has impeded QWIP development for a long time. Generally, an arbitrary choice of detector structures yields substantial variations of absorption properties, and QWIP was regarded as a low quantum efficiency detector. With the advent of electromagnetic modeling, quantum efficiency of any detector geometry can be known exactly and be optimized to attain a large satisfactory value. Consequently, all properties of QWIPs are predictable, not unlike prevailing silicon devices. This unique characteristic enables QWIP to be the most manufacturable long wavelength infrared technology in mass production.

 

This book by K K Choi, a co-inventor of QWIPs, will capture this exciting development.

Based on the materials expounded in the book, the reader will know key performance metrics in infrared detection, in-depth knowledge of QWIP material and structural designs, array production, its application, and practical knowledge of electromagnetic modeling. In addition, the book will describe using micro- and nano-structures to enhance the emission properties of active and passive optical emitters, similar to detectors. The application of rigorous electromagnetic modeling to optical emitters is new to the optoelectronic community. The resonator-pixel emitter structure with its modeling method will no doubt be able to attract substantial academic and industrial attention in years to come.

My bully LOVES these! She is an aggressive chewer and they don’t break apart. They are scented too which makes her enjoy these more

My Dog Absolutely Loves These!
Color: Multi color
My dog loves these Kimee chew toys! He’s a strong chewer, and most toys don’t last long, but these are truly tough and hold up incredibly well. The bacon flavor instantly got his attention, and now he plays with them every day. I really like that they come in a 3-pack with different shapes, which keeps him entertained and helps with boredom relief. The tough nylon material is perfect for aggressive chewers, and it even helps with teeth cleaning while he chews. Great quality, super durable, and definitely worth it.

Not Safe – Choking Hazard Concern
Color: Multi color
I purchased this toy based on its promise of durability and safety, but unfortunately, my experience was alarming. Despite being marketed as “indestructible” and safe for aggressive chewers, the toy quickly showed signs of wear and began breaking into small, sharp pieces. My dog almost choked on a fragment that broke off during a normal chewing session. The “food-grade nylon” claim feels misleading when the toy fails to hold up under pressure. No matter how authentic the scent or how entertaining it might seem, a chew toy that poses a choking risk is simply not safe—especially for strong chewers. I had to throw it out within hours of opening the package. Please reconsider your dog’s safety before purchasing. This toy is not worth the risk. Manufacturers should be held accountable when safety claims don’t match the actual performance of the product.

Great toy
Color: Multi color
My dog is a chewer and has torn apart many toys. These are great, they are tough, not soft, and don't get destroyed easily. I recommend these for dogs that easily destroy indestructible toys.
