Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 128 words
A connector for coupling an optical fiber transmission line to the package of an electro-optical semiconductor device comprising: a central body portion having a surface thereof complementary to the shape of said package; a pair of arms positioned on either side of said central body portion and extending away from said surface to form a pincer-like enclosure for said package; flexible coupling means interconnecting said central body portion and said arms so that said arms can move relative to said central body portion; each arm having an end portion extending orthogonal to the arm and defining a shoulder portion for temporarily securing said connector to said package; and wherein said central body comprises optical fiber extending at least to said surface for optical connection to said semiconductor device.
Claim 2
Dependent Claim 128 words
A connector for coupling an optical fiber transmission line to the package of an electro-optical semiconductor device comprising: a central body portion having a surface thereof complementary to the shape of said package; a pair of arms positioned on either side of said central body portion and extending away from said surface to form a pincer-like enclosure for said package; flexible coupling means interconnecting said central body portion and said arms so that said arms can move relative to said central body portion; each arm having an end portion extending orthogonal to the arm and defining a shoulder portion for temporarily securing said connector to said package; and wherein said central body comprises optical fiber extending at least to said surface for optical connection to said semiconductor device.
Claim 3
Dependent Claim 24 words
The connector as set forth in claim 1 wherein said central body further comprises optical fiber means extending a predetermined distance from said surface.
Claim 4
Dependent Claim 19 words
The connector as set forth in claim 2 wherein said arms and said optical fiber means are approximately parallel.
Claim 5
Dependent Claim 32 words
The connector as set forth in claim 1 wherein said central body portion comprises two optical fibers and a septum for defining two locations, each for receiving a packaged electro-optical semiconductor device.
Claim 6
Dependent Claim 153 words
A low cost electro-optical semiconductor device, adapted for being easily connected to or disconnected from an optical fiber having a pincer-like connector on one end thereof for engaging said device, comprising: a semiconductor chip having a photo-active area, a plurality of electrical leads having first ends thereof within said device and connected to said chip and the second ends thereof extending outwardly from said device in generally the same direction, and plastic package means for encapsulating said semiconductor chip and the first ends of said leads, said package having a flat surface portion on a side opposite the side said photo-active area faces for engaging said pincer-like connector and having a light transmissive portion between said photo-active area and a surface opposite said flat surface portion, wherein the arms of said pincer-like connector can engage the flat surface portion for temporarily holding said optical fiber adjacent said light transmissive portion of said package.
Claim 7
Dependent Claim 153 words
A low cost electro-optical semiconductor device, adapted for being easily connected to or disconnected from an optical fiber having a pincer-like connector on one end thereof for engaging said device, comprising: a semiconductor chip having a photo-active area, a plurality of electrical leads having first ends thereof within said device and connected to said chip and the second ends thereof extending outwardly from said device in generally the same direction, and plastic package means for encapsulating said semiconductor chip and the first ends of said leads, said package having a flat surface portion on a side opposite the side said photo-active area faces for engaging said pincer-like connector and having a light transmissive portion between said photo-active area and a surface opposite said flat surface portion, wherein the arms of said pincer-like connector can engage the flat surface portion for temporarily holding said optical fiber adjacent said light transmissive portion of said package.
Claim 8
Dependent Claim 19 words
The device as set forth in claim 5 wherein said leads extend in a direction opposite said optical fiber.
Claim 9
Dependent Claim 19 words
The device as set forth in claim 5 wherein said direction is in a plane orthogonal to said fiber.
Claim 10
Dependent Claim 102 words
A low cost electro-optical semiconductor device, adapted for being easily connected to or disconnected from an optical fiber having a pincer-like connector on one end thereof for engaging said device, comprising: an integrated circuit chip having a photo-active area, and a package enclosing said chip having recesses formed therein for engaging said pincer-like connector and having a light transmissive portion at least between said photo-active area and the outer surface of said package adjacent said photo-active area, wherein the arms of said pincer-like connector can engage said recesses for temporarily holding said optical fiber adjacent the light transmissive portion of said package.
Claim 11
Dependent Claim 102 words
A low cost electro-optical semiconductor device, adapted for being easily connected to or disconnected from an optical fiber having a pincer-like connector on one end thereof for engaging said device, comprising: an integrated circuit chip having a photo-active area, and a package enclosing said chip having recesses formed therein for engaging said pincer-like connector and having a light transmissive portion at least between said photo-active area and the outer surface of said package adjacent said photo-active area, wherein the arms of said pincer-like connector can engage said recesses for temporarily holding said optical fiber adjacent the light transmissive portion of said package.
Claim 12
Dependent Claim 17 words
The device as set forth in claim 8 wherein said device comprises more than one photo-active area.
