Silicon APDs can be used between 300nm to 1100nm, germanium between 800nm and 1600nm, and InGaAs from 900nm to 1700nm. 0000010092 00000 n The concept is based on utilizing the properties of tip-like electrodes to focus and enhance the electric field, to reduce the breakdown voltage and cell capacitance and to eliminate the needs in a peripheral separation of the SiPM cells (avalanche regions). trailer 0000005568 00000 n Although significantly more expensive than germanium APDs, InGaAs APDs are typically %%EOF H���lS���}��'�;��vb�q���I�8!! �ˉ�˺,����ÁlKH���u{w.�Gtp�~r{l�Ӊ���Ҽ.�^��lǘ��~7�*�x�z��J��CM�hb�Y�lw�vy���*�{]؇B{�?2���ƌ�Flˆ�l��˾�VϻJQV�A�0���T�;i�JǙ��n79T>�ozՋ�i��������~(+�A�P-�ִ�P�� ��lfo��HN�a�+$��y�W�vMf�(��T������0$��3ζ��b�!r��l�� �v���v'Uƍt��N� �}%���?���E�� Utilizing thin multiplication regions has reduced the excess noise.
